I have to go, so I'm not going to take the time to comment every single one, but I think you are likely one of the better photographer's here, at least in my book. After looking at everything you've posted, I've decided I love your work. With this one, the only thing I could really suggest would be having had the model not smile as much, maybe a little bit of a frown, look a bit more scared. Right now it looks like she is just kind of laying there thinking. The only thing that really suggests otherwise is the hair. Whoever she is, she's beautiful though
