Creative idea, good presentation, funny to watch - I'm glad that you submitted this, mate.
Just 2 points to mention:
1. The sound was a bit low, maybe tweak the sound volume next time
2. The end was a bit (just a bit!) dull for such a funny animation. A bit more action (the YouTubinator attacks with a special "red" weapon, for example...) in the final scene wouldn't be bad imo.
