No added value
This collab really isn't that good, the animation is at best mediocare and the music isn't that good either.
It looks like you just took a lot of random pieces, most of which probably wouldn't even get passed judgment and stuck them together.
Now I know you probably feel proud of your work but the fact you stuck it all into one layer... I just don't find the fact it has one layer too interesting or contributional to the piece itself.
Hope you don't find this offensive or anything, good luck and keep making flash.
