Well..
It seemed to lack any form of story line. And it doesn't make me want to watch or do whatever with the actual show, so I would say isn't a good ad.
The actual animation wasn't too bad. For the most part it was done well, but it seemed to be lacking any fluid movement, and due to that, its easy, and lacks effort other flashes give.
The sound was done well overall. The song seemed to be a little too quiet, and didn't fit the ad well. (I really like the song though ^_^)
You can do better, you show potential. I look forward to your next flash.
