Hills and landscape

I'm done painting clouds on the backdrop. Overall it came out not too bad. It's now time to think on how to paint the hills and the landscape. I still need to do some research to understand what one would see standing in the area I want to model. I've just played a bit with Google Maps and Earth.
Anyway, these are four photo I took last Sunday with my iPhone, so the quality it's not perfect.

See you soon...
