I hope I can get some art from you someday, you're great at drawing. The only thing I see is that her foot is at an odd angle compared to the rest of her body. Other than that, it's really cute.
I think the first thing to focus on is anatomy. There are several things that are a bit wonky; her arms, hands, neck, and leg. Also study references of clothes or simply look around your home at the way things fold and react to certain objects. Overall, it's really cute tho! c:
