I think this could be a lot smoother, this is how id fix the AAing somewhat, very rushed though didn't do it all..
This is looking great, I gotta admit, another suggestion would be to add in your shadowing onto the hair to bring the two bits dangling forward and the back hair, back.
For the anatomy I think it'd be a better idea figuring out the actual shape of this character, as in not forgetting the legs, even though its gonna have a long skirt covering em, the whereabouts of the legs severly effects what happens to the skirt and how you'd go about shading it.. you may even find youve made it too long.
I think the positioning is kinda awkward but so far your doing great.
edit- also I noticed that theres a few shades in your palette that aren't exactly needed, at 100% theres not atall a difference since theyre so close to other shades.
