pretty neat, you managed to build this super fast! a tip for future final videos: you seem to spend a lot of time in the beginning showing shots of the track without the train going around it. if you can, try to always have the train going around the course when you show it! :)
I would ask roller coaster crafter since he works with themes the most. He doesn’t really respond to comments but if you ask him in a livestream he will be helpful.
