Thank you so much for the advice Panzer. I'm going to rotate the crotch/shadow area and make the knee lower and shave off some fat, move the highlight a bit like you said. Of course this is going to be a lot harder to do with paint.. matching the right shades and colors and such. (That's the hardest part. Trying to mix the exact shade of paint over again.) But i'll do it, because that leg really bothers my boyfriend and I. And so far almost everyone who's seen the painting has commented on it. Thanks again. I'll show it to you when I think i've fixed it, (hopefully if I can), for your approval.
Unfortunately the kneecap is going to have to be moved right where you pointed out with the question mark, right where the quilt and sheets meet, which is kind of awkward composition wise, but it will still be better looking than how it is right now.
