Ok, this is meant as constructive criticism, and I seem to be alone in thinking this so don't take it to heart, also I may just be bitching because you get thousands more views than me , so ignore as nessecary
My criticism is this, the video doesn't start until a minute in! compared with fusionbly's 3sec intro
here (for example) the intro's 20 times longer than it needs to be!
We're on your channel already so you don't need to show your name again (twice) and by including the special thanks in the side bar you could include
links to each contributers channels that I think they'd appreciate (but I can't speak for them), you also include all the information again at the end anyway
Also, the warning about not pinching the video that contains portions lifted from other peoples vids seems hypocritical, but I don't know if you ask for permission or not so
ignore this bit if you do.
That said, I enjoyed the content and the lip syncing was outstanding so nice work overall
and again, ignore the criticism as nessecary
