I'm a huge fan of Pink Floyd...
love the song and thats why I rated your animation so high.
I was really hoping when I saw the title that the animation was going to be really great. It was mediocre though. Certain aspects were good, such as the explosion of the wall and when the guy dies and turns into a skeleton (similar to the Wall movie).
The lip syncing was off pretty bad in parts and just generally I was hoping for something a little more. With all the Pink Floyd art out there you could have really built an appealing tribute.
Though again, great choice of song, and you did a fairly good job. Keep up the good work.
