Liked the idea very much, but it needs some modification. No point of making the ground white, just leave it normal. The controls should be on brown details(since those are on the map), not rocks and marshes. Make more comps like this!:D
GREAT idea, and I see nothing wrong with using rocks, BUT not like no 1 where there was no way of guessing which rock to lookm behind - A proper description would have helped. I liked the track on the map that was buried in the snow.
