How a boring wash can turn all right

I wasn't very focused when I applied this wash. I used left-over paint and I didn't really have a plan.

All it took was an "I'm Feeling Lucky" in Picasa to turn a boring painting into a bright landscape from a psychedelic dream.

I'd like to do something with it, but I'm not sure what. The obvious would be to add a tree - at the top of the hill or the bottom? And what kind of tree? I think I'll park it for a time while I think about it.
