just dropping by here.. Colors are great! I think the pose can be improved though.
I recommend making it a bit more dynamic. She can use her right arm to sort of have a magic casting pose as well. Right now her right arm is just too static and doesn't add anything to the image.
Be wary about her belts. Right now her torso is too long.
They are mostly anatomical issues. The best way to solve this is by taking pictures of yourself in that pose in the same camera angle. That will greatly help out I promise!
Keep it up! I'm really liking the feel of this character especially the star/sun behind her.
