I think if you were going to add anything to this track though, it may be cool to see a few rock tunnels, even very short ones. Maybe take away the guard rails on a nice cliff side corner for an on the edge feel in certain parts. I think the current design is very creative and well done though, it shows a high level of intelligence in my opinion because you seem to have created it from a driver's point of experience with some nice sweeping switchbacks and compounded corners that go up and down as well as back and forth like a roller coaster. Just my 2 cents.
