That looks amazing, I couldn’t possibly make something like that. My only suggestion would be to work on composition a little. Its a beautiful scene, but it doesn’t really have a focal point. It would be cool if the camera made the bridge and the hand/roots of the tree thing two main focal points kind of close to the center. Of course, the problem with this is that it would be hard to get all the other cool stuff in the scene, which I’m sure is why you have the camera so far away to begin with.
