I don't know if it's good or bad that it has plain warcraftish look, but...
I'd recommend you started learning exotic effects and objects. You don't always have to import in order to create an exotic element, although it certainly
makes it easier sometimes. You can make your terrains really personal if you try to go down that road and express something you partially decide ahead.
For example, you could start by experimenting with doodad scales, tinting color (primarilly to accompany the desired light setting), Map Options->fog, doodad
(floating) height, and weather effects if they're interesting.
