It is so nice to see a model posting for critiques! I really dig your look and these images are really nice. As far as a critique of you goes, I think you rocked. But there are a couple of things that might be better if they were a little different.
In image #1 great control and awareness of your entire body. Your right arm isn't growing out of nowhere. I like it. What I would have a little more of is for you to have squared your shoulders up a bit. Too much profile for me.
#2. I feel like your eyes are poorly lit. I know lighting isn't your fault, but bringing up he chin could've helped that. If that's where the photographer put you, then shame on him.
