Images for environment art

So i decided i want a really nice drawing of an enviroment piece with the whole mountain. And the city in sight. To do this i am going to design it in layers. I think, yet as my graphics tablet is out of use for the next few weeks, i plan to start with sketch and work at it further by scanning it and going over it with graphics tablet when i have my tablet up and running.

I am going to look for images of real mountains to try and find one that would fit a dwarf town, as i view it. I am going to spend the rest of the day getting out large scale ideas for the mountain scenery.
