Welcome to Model Mayhem!
A quick note on posing: whatever is closest to the camera will appear the largest.
^Because avatars are smaller than the real thing, at a quick glance I thought this was a maternity pic. I'm NOT saying you're fat, I'm saying the pose and crop don't flatter your natural shape, especially at a distance. This one would be better:
Also, when choosing photographers, pick ones who know how to flatter a model with light. Most of your images are underexposed. Better lighting will improve your portfolio by a big step.
