So I took a look at the track and everything seems good! Like you previously said, you gotta work that insane inclined double helix... The gs are kind of scary! I'm not exactly sure what RMC's heart line is but this had NONE! For now, I'd recommend using the center heart line and tweaking based of pics/videos or if you find out the exact heart line is, just use that... other than that, what you have so far for the layout, looks really nice and clean!
P.S the crest of your lift seems a bit "drawn out", maybe try tightening it up a bit?
