I'm lost.. and bored.
That really made no sense to me what so ever. A rhino was sneezing at green triangles? The last shot looked like a DBZ rip off of a power up blast or something... well, it would have it was more than an expanding circle.
I don't mean to be rude, but I'm trying to be totally honest. I'm not into that style of music, but the song wasn't bad. Though I don't see how the song related to the flash in any way, and for as wild as the music was the animation was a bit bland.
It was very short, and it didn't have much of an ending. I'd go for making a basic plot next time, and perhaps some dialogue (in the way of subtitles at least) to help make sense of it.
Good Luck with your future submissions.
