I would use Dodge and Burn tools to give the portrait a little more depth. The face and upper chest/shoulder look kind of flat, like it is all one piece. If it doesn't upset you click here. Keep in mind I rushed this just to kind of give you an idea of what I was talking about. If you want me to remove the link just let me know.
I would change the font. Although I like the font, I have a hard time reading the characters name.
I like the layout, and the fact that you painted by hand. Not an easy task in my opinion.

The colors and the background image works very well here. Oooh ooh, maybe add a flower in her ear...Just a thought though.
