This has some great potential, like seriously a good attempt especially for your first mod.
A few problems I'd say is it goes from straight line to ramp to 'steeply' as in the ramp stage would be a lot better if it was a much smoother transition.
Another is i'd say the landing zone is to high, I think it would make more sense if the landing section was lower than the actual jump. The landing section is also not very smooth.
It looks nice but needs some work done, unfortunatley its gonna take a long time to fix it XD I understand if you are not willing to fix it since it would take so long.
I really appreciate you trying so have sent you 10k TC. If you can fix it i am happy to send more.
