This is high quality work, with a great visual style, good voice work and an awesome score. However, I'm not sure I got the purpose of the whole thing.
I'm assuming it's meant to be some kind of parable to encourage kids to eat their veggies, but the message is a little muddy.
Also if you're going to write for kids, it might be best to avoid using guns and liquor as heroic plot devices -- and it's certainly a bad idea to tell them how to make a mini flame thrower.
Pacing seemed a little off to me, too. Looks like it was designed with commercial breaks in mind?
Still, nothing some more effort in the writing department can't solve, and overall a very professional effort.
