Yea.. looks pretty good.. just a dash of color. I kind of like the mountains the way they are(though a bit more variety in brushes would not hurt), so if you do color the mountains, I would think a nice pastelish color would probably keep them from being overwhelming...

Opps... looks like your first post noted about wanting to change the mountains anyway...I think as a whole they are fine, at least in the scale of the above attachment. The big version in your gallery... that's another story. Anyway.. keep it up... nice work going on here.
