Great Animation, poor sound
The animation was very good, especially the lip synching. I found the sound to be the only thing wrong with this piece. The announcers popping and the muddy range were very distracting. I would redo the sound.
I also didnt like the music when the big guy was coming out. It was dramatic but too slow at building suspense. Something with more adrenaline would've fit better. This music seemed to belong in a sprawling epic, not a boxing film.
Over all you have a great talent and I think a little more attention to the sound production will help you go far.
