The video is fine, is it shot with a phone?
The composition itself is actually fine, but I would just practice those parts and get them tighter before putting it out there. The bass/guitar being off time makes it a tad jarring when the bass is so high in the mix, nothing wrong with putting out videos though keep it up as a way to look back on your efforts as you improve and you can always compare.
But yeah, definitely slow it down and get those parts down tighter in the recording process, work on the mix a bit and make sure elements like the bass aren't drowning out the other instruments. Keep it up!
