Man, that darn cat is everywhere. It seems like this drawing is much shinier than your previous anatomy pose, which I like. I also really like the pose, as it, with the girl's expression, really gives off a cute vibe to it. Your choice of lipstick color is nice and the shading you did with the girl's hair is awesome. The detail you put into the fingers and toes is also good (a number of artist usually ignore this detail or can't seem to get it right).
The only draw back I find is in the knee caps. The black curved line to indicate the knee cap doesn't really look good (perhaps some subtle skin shading would have sufficed), but that's just my opinion. Really good job dude!
