Enjoy The Ride

As far as the ride goes your banking was a bit off at times put it wasn't too bad. Remember you can usually cheat the auto-banker by around 10 degrees if you have to help your track out. I've found it sometimes makes a track wobble so I'll kind of "average out" the banking by hand to avoid that. Supports were fine and definitely adequate. Good job on controlling the G's.
Next time when you make a launch like that have a set of brakes (you had enough straight track) as a safety thing in case they want to abort the launch. Also have your train slow down a bit when it hits the water. Water splashes are pretty much a flashy brake.
Overall I liked the theme of your ride and I think you created a nice environment. The scenery was cool while not being overbearing, and you have good interaction with it.
