Build a track - Need YOUR help!

[Rebelgium]

The right corner on the top pic might be a problem.
When you com on the ramp quickly, you'll always overshoot and end up next to the track/neighbours... :)

I'd put and inclined turn in the top corner of the top pic.
You know, like in nascar races, a turn where the outer side is higher than the inner side of the turn.

And maybe, if you want more jumps, I'd put another single/double/triple jump on the track.
The best location imo is on the straight piece just after the top turn, assuming you're running clockwise.
