Work on your voice acting. I couldn't even make it halfway through the animation. Blegh. At least hire some people who actually know what they're doing, you know? Or at least try to disguise your voice a bit. Actually, your voice kind of sucks. Hire people. There are some voice actors out there who are willing to work for free, you know.
Also, I'm pretty sure most of your audio was taken from video games. There's only like... I dunno... THOUSANDS of songs and loops here on Newgrounds, each one ABSOLUTELY FREE to use? It seems idiotic to me, really. It's kind of like stealing a balloon from a party store that's right next to a free balloon stand.
