Aww. Love the hair with the shading and the colour. I like the little bits of green added in. You also use a different angle for the face. It looks good. I like the costume and the pose. It's very nice.

I notice she doesn't have any eyebrows. The way she's feeling might show a bit better if you just add in the eyebrows to show a lonely sad expression.
