Thanks a lot for the feedback
About the shoe thing, I think you're right; I should change the black ones to a shinier palette.
And the hand looks a bit strange, I've noticed that too. I don't know whether I'll change it, though; it would require changing pretty much every article of clothing and I kinda promised the person I got the base from that I wouldn't make any further edits. But I'll see what I can do.
Stockings are something I'm planning to add, hopefully in the next update, and I've been thinking of adding purses and bags as well. Sandals will probably also be included sometime, if I can get them to work (shoes are such a pain to draw XP).
I'll think about adding long dresses, too, but probably not in the next few updates. I'm definitely going to make some new skirts, though.
