I'm going to have to echo the claims of messiness, but only because of how ambitious this project is. I think the reason this build looks so messy is because there is too much going on for a build of such size. The fantastical aesthetic your going for requires a build of a larger scale so that the amount of detail you put into the structures to be made sense of. Everything just looks so cramped. I think it looks beautiful, though, especially the tree(?) and I love the color scheme..
