Wonder why I never reviewed this. :/
Other than the boot that is in front, this is pretty excellent. That boot looks distracting, and I think it may be the fact that it lacks dimension. I mean it looks like it's flat. And I know you didn't mean to make it look that way.
Nothing else is wrong with this piece really. I think Brush looks sexy as hell, I like the background and the coloring. Her eye's are sexy as hell. Wish she was waiting for me right now >:)
The rough sketchiness of the outline is a little distracting when I zoom into the picture, but compared to some of your other pieces it could be seen as a style choice.
At least that's what one who is less of an artist, like me, might think ;)
