If you look at my videos I always add a copy right disclaimer in the info and if they take the music out you can fill out a form on youtube to get your music back... basically just copy and paste the disclaimer and you should be fine!
Yea, MW2 colors are kinda funky and look weird sometimes in videos. Honestly though for a first video is was pretty good. Next week will honestly tell us more, it is always hard to judge a first video cause you don't have anything to compare and see where you are improving or where you are getting worse. Also, 30-40 secs of video makes it even harder to critique since there really isn't much there to critique.
