It's a nice piece. Much better than I could ever do, but it still has a lot of potential.

My biggest problem is with is the left hand and foot. Unless she has a condition that causes her appendeges to be ridiculously small, OK. But if she doesn't, then I would try to fix that if I were you were you, it's just kind of an eyesore whereas the rest of the character is pristine.

My other problem is with the background. There are no marks/lines indicating that her body is digging into the bed at all, leaving the impression that the bed is hard as a rock. And I noticed how you did that thing where you make everything in the picture blurry except for the main subject. (I know it has a name, it just escapes me right now.) You pulled it off well, however, when the floors met with the walls, the floor should've stopped, blurry or not, but they kept going just a little bit. That kinda makes me imagine the floor is covered in cocaine.

Despite these little problems, this is still a good piece. The shading/light perspective, you did very well, and all the colors blend well and don't clash.

Looking forward to more.
