That was very well done, one thing I noticed that impressed me was your ability to predict where and how you were going to hit other objects or buildings and adjust accordingly before the impact to add another bump or avoid bailing which is a key part of stunting.
The main area I'd try to improve in is picking your spots better, try to base your ideas around less bumps per stunts but more powerful ones to land higher buildings or cover bigger distances so that they seem less like random stunts-by-accident and more like a compilation of individual visions that took time, effort and a technical comprehension to accomplish.
I loved the fact that you used a lot of new spots instead of redoing or building upon new ideas, keep that up.

I'd give it a 8/10 but since it's your first I'll bump it up to a 9/10, I'm very interested in seeing what you're up to next

Bienvenue, are you a girl ?
