nothing wrong with this shot that a touch more contrast couldn't help. If a breast is bared, I say go right up to the nipple. Maybe a little buttocks cleavage is warranted here as well. Maybe its the testosterone talking- but if its sensual go for it- but hell I wouldn't know sensuality even if it came up and bit me on the ass!
Maybe a little too soft. This coulda been a great picture, but I feel the subject kinda blends into the background too much... and an excellent picture had the purple sheet been left out ; )
I think it would be a better idea to have the lady stand in front of a dark sheet because the background here seems to be a bit distracting. The pose is really good.
