bumpity bump! I like your videos, though as you say you should practice your aim
Im kind of in the same seat as you when it comes to C2 vids, I dont really want to do a commentary and putting in music often results in copyrights, so its hard to maintain a high entertainment level when every video is the same.
I just put up a video of me in TIA - parking deck, I speed up the video on the parts where I just run around and slowed em down when the fights actually do begin, personally I liked the outcome but other then that I cant really give you any tips.
