You got lazy.
alright, it was ok. I liked some of the animation and the style, but i've a few problems with it.
1. the music, and the sound. Dear god, that music was terrible. I can see where you were trying to go with it but the music didn't seem to mix very well with the action and the repeition of the same piece over and over nearly made me stop watching the movie, it just started to drill into my head.
2. Lets face it, you got lazy. There are some really nice sequences in this but some really crap ones over them, like when the tenticle thing grab the bee guy, you just used lines! come on, your animation is clearly better than that. Also, i think you shouldn't have settled for the nuclear blast sequence you used with the radio voice over, you could have cut the sound a bit sooner, dubbed it, or even used a diffrent shot. This toon could have been really great, but it little things like that that make it just mediocre.
You could have done a better job of this and you know it.
