Experimenting with water colors

Trying my hand at water colors with a little mixed media. Its all about layering and I discovered I'm very impatient when it comes to paint drying.
I still don't know if I consider this piece done. I might go back and add more elements. 
Can you see where I used table salt? Yup... in the sky. Such a cool effect! This is a medium I sure want to explore more with! 

Stage One- background. Watercolor and salt

Stage two- adding trees and road

Stage three- adding paper trees. Is it complete?
