Great work! Really nice, unique and well made ride. It's great to see what can be done with a little inspiration (from Twister, no doubt) and some time.
I liked the layout. I can see what Xpress means about it getting a bit slow at the end. It possibly could've ended a few turns ealier, just to keep the fast pace right till the end, but it was pretty good overall. Most of the trackwork was good too, there were the odd jerks and pumps, but nothing that I wouldn't expect from a handbuilt woodie. I also kinda liked the feel with all the trees, it was surprisingly hard to figure out the layout for the first time riding it, which is interesting as it's such a small ride.
Supports, well... I don't blame you for not hand-supporting it. Frankly I think it's only really the chance to be able to 'say you did'. You had to edit these supports, so that's enough in my book.
Overall, really nice effort. 8.5/10
