Not bad for your first! I would avoid using boosts if you can, but otherwise it was nice. Keep it up .

Nice stuff.  You and I have a similar eye as I spotted some on there I've not seen anyone else do before, but have done myself.  The one onto the Maze Bank Arena is one I tried to do a lot, but I was doing it slightly different from you and I couldn't reach it.  I'll change it and try again, now I've seen it done.

Also, check out this one I made.  You do the first jump pretty much exactly the same, and then something similar to the second, but a bit further inland.

There was quite a few on there I hadn't seen before, which is always nice.  Keep it up man
