Before you submit any photo ask yourself is this of any interest to the viewer am i causing embarrasment to the model does the image have any artistic merit, and this picture whilst the camera technique is good, the composition is ungainly, and the model definitely looks embarrased. 4
I find her to have a very unique look. I would have prefered her to have a possibly different pose to go with such a happy expression...or a different expression to go with her pose. However, she looks rather comfortable with both her pose and expression.
Your model is center of picture, but in my tastes, this isn't "tastefully done". It's got a more "snapshot-tacky porn" look to it. I don't mind nude shots as some of them can be quite tastefully beautiful, but this particular shot just screams "shock vote value" rather than artistic class.
