Nice try, but a blatant SMBZ attempt.
It seems you have some potential as a sprite-flash artist, but anyone who's been to Newgrounds could see you were imitating Alvin-Earthworm. The music, the characters, and those "critical hits" (which were a bit overdone in this flash IMO), and the fighting style are examples of this.
This was a pretty good attempt, I would say, and you've shown that you do have a bit of skill, but next time try to be more original and use your own ideas. Nobody has a patent on Mario and Sonic sprite videos, but use your own themes and less clichéd music.
