Good or bad, Good or bad! Its...OKAY! Wait. What?
It's a great picture except for what roxsora69 said although I think he meant the right nipple (from her side) although it is twisted in a not to show its apart of the shoulder the illusion makes it seem like it is too close to the viewer as if it is her nipple. So from a certain point of view it appears to be like a tent formation coming from the nipple. Also I was not too sure about the hair whether it was meant to be "puffy" or laid out on the bed. If it was actually made too look laid out then it should not be so out from top too bottom, you should try to make it appear flatter
(if the hair is supposed to be on the bed and not poofy, ya know)
