This is a racetrack I have been working on for about a couple days just to see what I could get, and here's what I got so far (all of the pictures are in order according to the track): Starting Point First Drop Split First Bank Rainbow Tunnel Straight(Landmines) Spire Bank Last Bank Overview That's what I got so far, let me know what you think. I was thinking of changing the Straight to something else but I don't know what. Also, I was wondering what I should do next, but I'm stuck there too.
I'm not sure what you could do as an alternative for the straight portion (but I think that the current set up looks nice enough). If you're fine with a relatively shorter track, you could just put a vehicle teleporter at the end that you already have that brings players back to the beginning. Other than that, this looks very nicely forged. Everything looks extremely smooth; well done.
