well..it seems a bit empty and not very templish even if it was ruined. the "mountain" looks pretty unnatural and void of doodads...i see quite a few floating trees also. Add in some environmental doods and maybe some things for the temple.
I think, like a lot of terrain, that your problem is lack of appropriate or fitting doodads, and also tile variation, especially on the mountain. Add a bit more of each of these and it should look good :D
