Hey bud, you have some really good stuff here. A few thoughts to further refine...
#12: We really like this one although want to see more options... maybe no sun or a muted sun. Want to see additional options with an A (for Activ) as a mountain. Cool angle
#14: We like the concept although the logo is too big. Let's try a couple along this line but where it logo is smaller
Colors: Orange and grey look great together. Could also try a nice green and grey. Teal and grey could be cool as well...
Definitely like where you're going with some of these designs!
