If this is your first time using Vegas, I applaud you! You did a pretty good job!
The only things I'd critique would be that some of the edits were a bit choppy, you didn't cut in time and the next scene would flash for a frame. Also, if you were going for syncing the cuts with the music, most cuts were either too early or too late, as well as the drops not being emphasized. I agree with Idec, a lot of the black screens were a bit too long. Not much of a critique, but using Xbox's Jump Ahead trailer in the finale doesn't really match what you are going for, and could give you a copyright strike.
Regardless, keep working at it! Editing takes a ton of practice, so keep making these and they'll get better every time!
Go ahead and critique my channel if you'd like, I'm open to any suggestions!
