Thanks for the comments and help! I changed the colors of the footers, used caps for the corkscrew supports and removed the original support underneath the helix using Blu's trick. I think I'll change some of the supports (and add flanges) but this is how it looks at the moment:
I also changed the coaster into the "extended coaster" (floorless cars) that can be found in the Wild! expansion pack. I did this so that I could place diagonal trim brakes inside the second tunnel.
