The concept's good, but like most of the intros, you did two huge mistakes. Or three.
a) The background is static. It's pretty boring to watch an intro when it's static, considering the letters and logo are moving.
b) Sound effects. You should of added an ambient sound effect to combine it to the smashes, cause right now they sound low quallity, but with that you could disort them :p
[s]c) The materials have no reflection on the background (the static image), but this is not necessary, that's why I strikethrough'd it.[/s]
