My god, that's just incredible Julia!
My only feedback right now would be that the big toe on the foot closest to us looks a bit strange. I'm not quite sure why actually, but it looks slightly off to me. It might be just a personnal preference of mine, but I'd make her hair darker. I feel it would frame her face better and make it pop more.
Also, don't forget that she's surrounded by green pretty much everywhere, so I feel there should be some green bounce light on her, especially on the parts touching the ground and mabe the shadows. No need to be too obvious with it, but I think it would help make her fit into the scene even more.
Beyond that though, it's looking great. I really look forward to the final result!
