I've seen her on Model Mayhem before, and for some reason, I can't get past her teeth. Something just distracts me about them.... the front two looks larger than normal or something...
I do agree with Scott. If these are indeed for her portfolio, you edited way to many. 2-3 shots max per outfit. I know you only had 1 outfit. If this for practice and fun, then go crazy! If you are just starting out with model ports, its really easy to edit to many, but for continuity, probably needs to be narrowed down. Plus it saves you weeks of time in front of the computer.
I'm not a big fan of the sepia and black & white treatments, just because in the b&w, #8 in particular, it looks like she has a black eye.
#6 Good - but watch the backgrounds and stuff coming out of heads. This is commonly done, and I've done it myself before.
#10 I think this would be better if her hands were just dangling, and not one on her face. Would have liked to see both eyes too.
#13 Too much flash... might be the look you are going for. I personally like the use flash without it looking like you used flash method. The angle is really distracting. From a certain angle, almost looks like a belly bump.
I really don't like the outfit, and it seems you didn't either...The color is good, but the way the dress is, it makes her breasts look way too large and unflattering.
Your framing is pretty good on these. Just keep practicing!
