Good shading and the plant that's there is cool too. Nice details on the sailor uniform too.
But...
...I'm sorry Sorry, but I can't agree with PSB this time. No offense or anything, but I'd like to point out something it's looking weird to me in that pic.
If you were aiming for proportions, Sailor Misty's head is quite big compared to the rest of the body. I can't judge about the hands, as I cannot see them completly, but remember that the hand and the face of a character must be proportionally the same (more or less!).
With Misty's big head I get the feeling the legs are too short for her.. but maybe it's all because of the head.
Hope this helps you for future pics :)
