I gotta say, you seem to draw all your girls with such tiny waists, I can't really see how she could support such massive tits. Also, the breasts are magically pushed together and look more floppy and natural. It strikes me as odd looking. It could be nice if your girls didn't look like they were either breaking their knees or completely pigeon-toed, too. I know it's meant to be sexy, but it's unnatural looking, and I think you're getting to the point of drawing that sort of thing without thinking about it or trying. Do some more figure studies, maybe, if you aren't already.
