Curving out trees

Wow! It's almost a month since I updated about this painting last time. Saturday drawing class is an excuse but not good one. I could have spend more time on this at weekday nights.

Anyhow, after putting more layers on the sky (I did this weeks ago), I wanted to work on the ridge, to make it better. Instead of trying making better colors of the ridge, I put shadows of the trees on the valleys and curved out those trees by putting more layers on the reddish soil on the right hand side. Now those trees are more trees than just smudges of greenish paint. I need to do the same on the left hand side as well.
