I think I like #14 the best, however people are telling me the volcano looks like a hat! Any ideas?
I was thinking reshape volcano slightly , add more "ground" on left of volcano and add Mountain biker. Open to your ideas.
On # 15 - I like the idea of trying to make a volcano out of middle of wheel but not sure if it will work. Maybe you can try using a Trispoke wheel (wheel with three spokes) like Hed3 -
