Firstly i love the hair ~. you've pulled that off really well.
It's over all a really pretty sprite. But. the body needs some shading work Sir Seph. The far arm in my opinion is shaded too light near where her clothing ends because there wouldnt be much light hitting her there. Also the shirt/dress. Where her bewbs are, it would be more clingy, so more shading round there at the bottom would make it look more realistic. Since hopefully she is wearing a bra..to stop them falling too low.
and maybe this is just personal preference, but i think her eyes are too dark. they look slightly lifeless. maybe a lighter grey?
