I'm open to criticism, so feel free to tell me what i could do better next time....
....nobody asked what you think....
Moving on, the video quality isn't the best. I know it's hard to record PB, probably the hardest game to record I have seen so far, since it's so fast paced, but maybe try to work on that. Also the resolution youtube accepts so that you don't have black borders is 1280x720 (or any 16:9 resolution iirc), so try to render/record your video in that resolution. You could try messing around with different resolutions while recording, because the lower resolution, the easier it is to record the video (easier as in not that computer performance heavy). If you want to record the video without black borders, you gotta use 16:9 resolution ratio.
What I found is a good idea for PB video, is to cut the top and bottom so that viewers can't see the ammo or chat, but can still see eliminated at your crosshair. Just have a look at some of d1e's frag movies. Although it's just my personal preference.
Another thing, if you can, try to remove the ad for the app you made the video in, that was really distracting for me.
Otherwise, the editing was actually pretty good, not a big fan of the song, but you edited the shots to match the song rhythm which is good and makes for really good flow in a frag movie. It's still not as perfect as it could be, but you are on a good track with this
.
Some of the shots are kind of boring, but that's to be expected since you did this in a span of one week. If you just wanna learn how to edit frag movies properly then this is the best way, because you don't want to waste good shots on a frag movie, when you have no idea how it will turn out.
TL;DR
improve: quality, resolution, editing app
otherwise, nice to see that you actually put some effort into it and not just slapped some shots after each another and clicked render.
Good job
