#44 is really good and it may be the winner. I like the gap between the mountain and the road. I like the way the road ends above the "AR". I like that the mountain is the full width.
I would like to see a couple variations on it:
1. make a version that has that mountain a little taller, as tall as the mountain in #43
2. make a version with a slightly more aggressive mountain, but with the same gap below, and width as #44 (such as the mountain in #13 or #12, but a single color)
Thanks and good work.
