I really like how you did the curves of the demon girl. The way you got the Torso to curve off of the hips (which look very good) is pretty sexy. I think the left girl above the Hips should be moved slightly to the left.... I dunno though. The way her legs crossover to show off ass was also a nice touch... I suppose it looks like a dump is present, whatever. I guess that could be avoided by making the left line of her crotch curve to the other side quicker... I have no actual idea though, it's alot easier to look at finished drawings and tell what little tidbits to change up. I draw like shit, so ya know. Don't take my word for it. Overall your girls are getting better.
