Yes I do agree that the white part distract it. Try to use a clone tool to put some bushes there. That might improve it. Green is not my color and I think that the aquamarine clashes with the green, but thats personal. Perhaps you can recolor them to a color in the fairy cluster?
I love the way you stacked the bracket frames, and they may need some shadow but I am not sure, just play with it and have fun.
I hope this helps. Let me know how it turns out :p
