I think it looks really good.
The only thing (after a fairly quick look) I think needs to be changed would be to reduce the highlight on the mountains (it's very white and bright). Maybe lower the opacity a bit or change the color slightly.
Another thought... I would think that the 'elemental cogs' would be more more Earth, Air, Fire, Water related than what they currently are. Or is it supposed to be Spring, Summer, Fall & Winter?
