My basic idea contribution would be to just draw out a long and winding road, slap some trees around it, and set up some road blocks for orcs or goblins to jump out of. The challenge is quite challenging and I think most people are trying too hard to come up with some unique idea. Keep it simple, road and trees. Make it long instead of square. Don't let genre get in the way, if your road is gray then some yellow paint down the middle turns it into a modern street If it's brown then it could be any genre.
