sonic=sega, not nintendo. This had some potential but think of a better name and dude, it was like 4 seconds long.

nice

sound is from naruto

uhh

Sonic and Knuckles are Sega, not Nintendo, 2 of the backgrounds were just a colour and the music continues after it finishes. You shouldn't really submit unfinished work, and it didn't really seem like a trailer.

Characters move fluently though, so it's clear you put work into animating the sprites.

Could be cool, when it's finished.

Not Bad at All...
Just one thing ... when it ends the music continuous....
