OK, let’s see if this goes faster this time, since I king of already know what I’m going to say. 
TRT: Looks pretty cool, but I actually like the original version you did better I think. The markings had more personality to them. I didn’t update the gallery with this new version since I think the old one is better, but if you’d rather have this new one there, please let me know, and I’ll gladly switch it in for you.
Rook: Sweet Cody. He looks totally ready to kick some ass. My main critique for him would be to throw that back arm into shadow so that is sits back more and also helps to frame the forward hand. Very fun Chun concept you got there. Even though what you added was simple, you did a very good job of placing her into a believable environment. I agree about seeing less buttcrack shadow since she’s in a towel, however, I think some more folds in the towel would help bring her form out nicely. Also, I think she could use wider hips and beefier legs. She is Chun Li, after all. 
DFist: I got a picture crit for ya:

It kind of shows how the hips might work, but mainly it shows how small tweaks in the pose with consideration to lines that counter each other can make for a more balanced and flowey pose. Also, spacing the arm further out from the body makes for a more interesting silhouette. The cammy is sweet as shit. I’m lovin the bold color choices and the overall idea of the pic. I think that the buildings in the bg look just a little odd how they are. The way they’re not quite straight and even looks good and fun, but it looks like it belongs with a cartoonier drawings rather than your realistic Cammy. The Honda cracks me up. Fun idea for a picture. I think one thing that throws me off about it is the way his fat is distributed. For some reason it looks kinda more like the way fat looks on a fat baby, where it is overall chubbiness fairly evenly distributed. I think on an older guy like him, it would hang differently. Go check out some fatties, yo 
VSlash: Cool idea for a pic. You did a good job of differentiating the two characters by their expressions too. I think that the ear placement is just a little high, and that the cropping of the pic right in the middle of Guy’s finger looks just a little odd.
Zakuta: Nice pic, and nice attention to detail. One thing that strikes me as a little odd is that her pose suggests that she is moving left, but her braids suggest she’s moving right. It’s important to keep your dangling objects and drapery moving with the flow of action to accentuate it. Also, be careful when things line up perfectly in a pic; right now, her braid is kind of coming out of her elbow. Can’t wait to see the colors!
Switcher: Very dynamic Cammy there. Nice way of showing the action too. I think it would have been good to include her right arm in the pic too. It looks kinda of like she doesn’t have one, and it would make sense, balance-wise to have her throw it behind her far enough that we would see it, since her left arm is so far forward. Also, composition-wise, be careful not to crop your edges too close; I think her head and her shoulder could use a little more breathing room.
Munta: Booo, Delta Red. j/k
Cool pic, and nice detail on the boots. I hate drawing shoes. The foreshortening on the forward hand looks just a little odd. The larger hand suggests that is is closer, but the angle and perspective of her arm doesnt’ really match it.
Mint: Very cool quickie you got there. Nice looseness, and great suggesting of forms without actually drawing them in. What’s with the dotty colors?
SeanCarlos: Welcome to the challenge, dude.
Cool slight blur to show Cody’s fist in action. Nice rendering in general man, very smooth. Don’t be afraid to pop some darker colors in there. With the exception of a few spots and the blacks in the Cody pic, you’re using mostly highlights and midtones. Some darker areas would really make it pop more. Another thing that helps is to vary your color choices more. Instead of using a darker version of the same color for shadows, consider changing it a bit to maybe a cooler or warmer color. Also, in skin, certain points in people tend to have more blood flowing to them near the surface, so they get pinker and redder in those spots (usually most noticible in places like knuckles, fingertips, noses, ears, cheeks) and this helps bring out more realistic skintones.
