Not too bad guys.
~ Animation/Graphics ~
Reviewing collabs like this isn't always the easiest thing because sometimes some people are really good, some are alright, and some are really bad. For the most part I can say that nobody was really bad in this. I will admit perhaps a few weak links here and there, but for the most part not too bad. Some really good ones and some decent ones. Can't really mess up a dot too much can you? XD
~ Story/Content ~
I liked the ones that went from just being a dot into turning into bigger things. Perhaps a couple more of those would have been better. I though a lot of the backgrounds used were really fitting. Even the ones that looked like they came from google. :P
Decent idea for a collab. Not really a great idea by all means, but I think it turned out well. I hope your proud of it.
~ Audio ~
I like the song, but I think you should have used a song from the audio portal. I'm never a fan of using copyrighted songs after having some of my youtube videos have their audio disabled. Fuckers. Song went well with the animations though.
~ Overall ~
Not too bad. Good job on this and good luck on any future projects.
