Looks really cool. I'd love to see more. Maybe add a bit more shading/differences in lighting on the actual character so it looks like they're actually in the forest.
i think you have a good start, but i would explore a little more the different types of media that you can put together. maybe try photoshoping parts of a painting into the forest so the forest is half photography and half painted? you can also try given a context to the scene. why is she walking in there? did she see something there?
hopefully i'm not making this more complicated than it needs to be @@ good luck!
