I might say, I quite really like this.
Her outfit, I might say, is very relevant to your character, herself.
The pink hair and the purple ribbon blends perfectly with her maid-like outfit. the stitches on her face and hands make it look like that she was somehow, involved in a tragedy. And I like that.
However, I did see a few mistakes, such as; the plants in the background look unlively and dull. Maybe because it doesn't have much shading. Unless you really want it to look like that. Secondly, the lighting is a bit deficit, I say. But the shading is absolutely wonderful. And lastly, her foot needs a bit more work, though. The rest of her foot looks like it disappeared when the clothe of her skirt went on top of it.
But, on behalf of all that, I say this is a very wonderful piece. Well done!
