Hi there! I like your style, its super interesting. I like how you combined the colors and show light and shadow in a simple way. How you focuss the attention to the girl is cool sort of like a spot light.
The only thing I think maybe you could ajust or pay attention to is the branch that hist the writing. It feels like there is a tangency happening with the writing maybe you can have it lower but still pointing at the writing, or, in the other direction pointing up to the name and the girl. I think that would give an extra element to help focus on that girl and the eye would follow where the girl is.
Other that that its a nice piece. keep it up. :D
