Pretty decent.
I noticed a lot of small things that slowly pulled the score down from this little by little. Let's start from the top... and by that I mean the top of the picture, which would be her legs. Looks right between her hands. Oh no white space that shouldn't be there! I'm assuming you forgot to magic eraser that out and turn it into the background?
So let's work our way up her body and down the picture. There's the white space again between the breast and the arm! This is where I wasn't sure what you did. If you make this part the background then it makes her body look rather weird. Her breasts are already odd shaped, but this would really through off her chest section. If it were part of her shirt it would probably look a bit better.
Other than that it's a decent piece of art all in all. Like I say for most pieces of art it would be cool to see her in an actual background instead of just against the transparent grey of newgrounds.
