Good idea, nice model. I think if you did some post processing (photoshop et.) the photo would be much nincer.- Remove zit from chest, ajust light and color (seems to be off some). Remove bra strap.
The right side of the face is is alittle too dark and I think if there was a reflector to bounce the light back to her face may have helped abit. Just my opinion
Excellent photo. Some observations that may have improved it a little. The shoulder looks a little odd, hunchec a bit perhaps or crossed in the lap. I like the side lighting, but might have liked it a bit better with soft light on the front of the face as well so as to have less harsh shadows. I really like the crop and general setup/use of props. Also on her forehead seems to be a bit of a purple tinge to the light. Nice use of thirds, as well.
This has potential. Lighting doesn't seem quite right to get the look I think you were after. The background didn't come out true white, which would be stronger. Some fill light on the right would help, and nice sharp focus on her eyes is important. JMO of course. Good luck in the challenge.
