I'd say to remove the kill counter for, Tom. We can't see him, so what's the point? At the start we don't even know where he is in relation to you. Maybe replace it with a death counter for yourself.
At the start I thought you were going to keep cutting from your view to his, to show how you flank to support each other or something. Once I realised it was just footage from you the second kill counter was just a distraction.
Aside from that, you could've altered the video settings a bit to make it a little easier to see in the darker areas at the start.
Otherwise I have no issues, it's no better or worse than any of my videos, I think the footage speaks for itself, it's clear enough when you hit someone and are hit yourself and I don't think fancy editing or anything are really required for casual games, so yeah, no major complaints from me.
