It would be nice if you could somehow combine the T of Turn with one of the peaks of the mountain. Maybe play around with having the T be green. I like the symbol much better, however, the sun looks almost orange. I like the color of the previous yellow that you used in the first sun in entry #3. Thanks!
I like the concept of #15 but would like to see the mountain flow more smoothly with the T and N. In #16 I do not care for the Ns. Maybe try a different looking N. I like #14. It would be interesting to see #13 the word North in a different font. I like the green in the mountain #12. The other greens are a little too bright.
