the subject is well positioned. The lighting seems a little off - the skin is glowing from the flash in a way that detracts from the artistic look you were working towards.
I think a different light setup might have added some dramatic shadows. Focus is good, as is the dof. Good use of black bg to contrast the model. Good job.
Front on flash is not too good for images like these.
I think the top scorers have put more thought into subtle lighting which emphasizes the contours of the body.
Your model has good skin tone and looks to be in shape. Imo, I find the picture pretty static and the lighting flat. I don't think I will say anything else. Sorry.
I'm guessing this is a self portrait. A great figure study, I just feel that the pose closes you off a bit. I think something else added into it to create some additional interest could have worked as well.
The way the arms are makes me feel that it is crooked. I do not like the lighting. Looks like you used flash. I am not so sure this is what the had in mind.LOL Good luck
blown out highlights from lighting (flash used?) are obvious and stand out. My only other comment is that you seem to have actively tried to keep this a very annonymous entry by cropping the shot at the neck... usually such a crop is always a bit wierd.
