Nice work. You´might need to tweak the envelopes of the bones a little because the arms and legs look very unnatural when bent. But that shouldnt take that long
Elbows and the knees dont overlap while bending. Usualy two bones share some same points and if one of the bone moves it makes it look "smooth". THe "edges" of the human body seperate the two muscles of it and only some skin over it is moving. That way you can bend the arms and legs wihtout bulging the other side of the bone chain. Sounds complicated but thats just because i suck at explaining

Overall I like it. Too bad you didnt skined her a little bit better. Some shadows on the clothes may look a lot better. Also if she is not a super japanese geisha she might be a little too bright.

tris count would be nice to know
