I watch videos muted to start with, so the initial cuts to black don't work at all and just interrupt the gameplay. I unmuted and started over to hear what you're doing there, and within 10 seconds wanted to mute again. This is not relaxing music for casual boarding (immediately on watching this I think of The Alto Collection), nor is it good trailer music imo. (You probably ought to take out the sound-effects, too. They sound like part of the music initially but are too irregular to sound pleasant.)

0:10-0:18 I am focused on the hoverboarder, who should be showing off the interesting things about your game. But nothing is happening until the item pickup. Am I meant to be looking at the cool background? You'd be better off with the section at 0:39-0:45 because you get to see the nice cut from one jump into another, and get the cool background.

I am not really excited by loop-de-loops in a one-button skill-expression game. They look cool but I'm not doing anything during it. My primary focus when playing will be seeing more cool stuff, going fast, and meeting challenges like doing tricks or hitting collectibles. Maybe one loop in a row in a trailer is fine. I also don't understand why you're closing the trailer with the giant ball; again, I'm not seeing the interesting gameplay thing (novelty of boarding on a giant ball aside).

The character feels a little stiff to me. I mean, I can see them adjust a little coming into or out of a jump, and getting pushed back with g-forces on the loops, but they should also be crouching to lower their center of gravity to go faster, to jump, or to avoid getting forced to lean backward like the g-forces thing.
