|You asked for my comment so here it is :) This is not a bad shot and if this is only the 2nd time you take a real stab at portfolio photography I can´t wait to see more. However, there are a couple of things, her pose first. Having her knees like that in the frame kindof draw the attention there, I think sitting more straight and bending the knees to either side would have helped this photo. I don´t usually cut off the head like that when shooting a half body photo, sure it works sometimes but here I think I would have wanted to see her whole head and maybe what´s behind her, so also the slight looking downard at the model is not maybe the best way to go here, I don´t know what was behind her so maybe I am wrong but that´s just my impression of the photo.
The rest is pretty good, good lighting and focus/dof and all that is like I said, pretty good.
