heheh oh, believe me, I'm old hat when it comes to critique. I just always try to test the waters before seeing what level of critique folks prefer. My favorite kind usually is very straight-to-the-point and matter-of-fact, efficient as I can get it type critique. However, some folks see this as harsh, others see it as a rite of passage. lol. Well, I suppose maybe not that bad, I tend to get a bit blunt if I don't watch it. However this of course in no way negates any positive feedback. I will mention everything that's going right as well as anything that might be not so right. And every critique I do is to help the artist improve what they might find will best evolve their individual works, not to cut an artist down or make them feel bad enough to quit. Heck, I ban those sorts of folk over back home. ;}
I suppose this is why they started calling me Sergeant Merekat over on the MT forums, but that led to the Boot Camp tutorial thread, so it can't be all bad, eh? :}
Anyway, I'm working on a paintover of Barb's page to make things a bit more clear than just spouting words. I do apologize if that step is a bit forward but sometimes pictures are worth quite a bit of words, etc. ;}
Will edit this post with it in a minute.
[edit:]
Alrighty. So first off, I'd like to commend you on your excellent character designs and lighting decisions. :} Very well done and I'm amazed at your nuances and details. In particular, I'm very impressed with your ability for profiles... those are by far the hardest I've found and your panel two seems to effortlessly pull them off. I can't find any fault with the faces, they're pretty darn schwell! ;}
You may want to watch the taper of xylia's neck towards the nape, but it's not bad. And you may want to consider downplaying the darkness of the jawline in such underlighting... or turn those lines more to the bright highlight color. There's a bit of conflicting information with the dark line being in such a light place.
But because you do profiles and 3/4 views so very well, I'm a little amused at some of your front-view treatments. You seem a bit unsure about form and placement concerning some of the facial structure.
From the front view, the side of the eye socket and the cheek structure meet at the temple to fill in the side of the skull. Check Liria's avatar for reference, but as you can see, from a straight on point of view, the side of the head would not cave in so. If it were like your drawing, her skull literally would be peanut-shaped! ;} Please excuse the playful analogy, but it seems as if you're mixing straight-forward features with a 3/4 profile silhouette. As you can see on my paintover below, I've straightened this out and added some more highlight according to the structure of her features.

Next I took out the deep lines between her eyes. I know this may somewhat help in line drawings, but if you're going to be coloring the images as thoroughly as you do, the deep lines in my opinion aren't as necessary and help to make her kind of fish-eyed.
I also tweaked the eyebrows a bit, but this is more my personal preference for shape. However, the length I think wouldn't extend so far over her eyes to the side of the head. And to make them so very evenly thin makes them look a little drawn on rather than actual hair, even in style. You might note the little tweaks in the inside brow with highlight and shadow to emphasize the expressing in this lighting.
As for the mouth, I replaced the dark underlip outline with a highlighted version, keeping more in synch with the lighting scheme. By keeping the dark line, you're portraying the information that from chin it dips in and out and then in and out again to the lip, so more like a ridged french fry. By omitting some lines for the sake of your lighting information, you'll more aptly tune the expression and impression to your intended atmosphere.
I also darkened the bottom lip into shadow for the light and highlighted the edge of it more directly.
Lastly, I worked on the tear. Because you were illustrating the lighting and environment so realistically, it seemed appropriate to bring the nature of a tear more in tune with that. Remember, they follow the shape of the face, including the lower eyelid. Yes, I did exaggerate the lid a bit more to show the lighting, but you get the idea. ;} The trick to water drops and streaks are very similar to lighting an iris, which I'll also explain in a moment. First, find a bit of a shadow tone... something maybe 2 shades darker than what your surface is. Streak that along where you want your tear to run.
Next, plop in your highlight on the side of the light where it'll hit the sharpest. It won't be as big as other marks, but it will be very direct and probably the most noticeable in contrast and intensity. Next, because light travels through water, you need to illustrate where it refracts on the back side of the drop. Also, because of your secondary blue light source, this allows us to have the sweeping stroke I've put on the upper right of the main drop at the end of the tear.
Next is the streak itself. Because of the run, it won't be the same thickness as the final tear, so it doesn't necessarily have to have highlight all the way up the streak. Only where it pools slightly at the fold of the lower lid on the cheek will it have enough to start behaving like a drop again. In which case, you can see I've put some of the highlight and refracting of the main drop into that shape. But as you can see, it's not a full and direct streak and behaves much more like a liquid.
Furthermore, if her eyes are wet enough for a tear, they should appear more moist and have a bit of pooling on the lid edge before it spilled over. I have exaggerated it a bit here, but I illustrated it just like the main tear, putting down a light stroke of tone before some highlights. This would cover somewhat the appearance of the iris, so make sure that is softened just a bit.
In keeping with the overall lighting, I also darkened down the whites of the eyes just a bit. By keeping them so white, they didn't look in key with the environment, and they're not forward enough in the face to get past the cheeks and be lit by your underlighting, so they had to be toned down.
Light works like a gradient. There is one place it hits first and that is the brightest and most intense location for the saturation and highlight. But from there it fades off and things it hits next will not be as strong or vibrant as the main highlight. The quickest way to flatten your painting is to highlight everything with the same intensity, for then you're telling the brain through the eye that everything is at the same level, therefore flat.
I probably should have toned down the forehead just a bit to make the chin and the cheeks read first, but I figured that might be a bit much for a first paintover. ;}
Now as a last comment on the irises... As I had mentioned, irises, being a feature below a clear substance of the lens works very similarly to a water droplet. You were absolutely correct to illustrate such a strong highlight at the bottom of the eye from the direction of the light source. However, as light will continue to travel through the lens, it'll hit the back of the iris for it's greatest color. Yes, in this lighting it might not be quite so extreme as in directly sunlight, but it will still have impact.
Here's a photo example of the lighting on an iris:

As you can see, your strong highlight is absolutely correct! ;} But the lightest part of the iris is on the opposite side of the highlight (and the shadow side of the white is a lot darker). Here's a simpler more anime version:

Same idea, a bit less detail.
Oh, and I also tweaked his thumb. Remember, the body will self-shadow as well, so the form of the thumb casts a shadow on itself... particularly the cuticle form shadowing the knuckle a bit. They're tiny details, yes, but that's where the magic is. ;}
Finally, PS... Pay no attention to the folder I put your image in. It's just my catch-all dump folder and wasn't a commentary on your painting. ;} I think everyone has a folder like this, but I always worry just in case there's misinterpretation.
Anyway, I hope this helps and that I explained everything well. Please let me know if you have any questions or concerns about what I did. I do love your work and can't wait to see more of it. ;} Just thought these tidbits might be some tasty food for thought and you might find them useful.
Looking forward to your next update! Keep up the fabulous work!
Oh and remind me to track down a good tutorial I have that can help you with a lot of lighting information. It's one of my favorite references and I use it quite a bit myself.
