I like the maps here:

However to fit with the style of my map, they would have to be less "plastic" looking.
These mountain are also cool:

I like the whole lack of perspective... the mountains are just viewed from above, like my forests. I don't like a lot of the perspective mountains that use shading and light angles... it messed up my eyes when I look at a map.
