I don't know what you're talking about...
I don't think it needs improvement. To be honest, even though some people make fun of things like this because they say it has little-to-no good animation, I say that's stupid. In my opinion worrying about the animation having excellent drawing such is pointless, because if someone tries to use that in order to make their cartoon look good... I examine it more thoroughly and tend to find flaws rather abrasive to quality of the movie as a whole, when in opposition a film like this I would just consider it along with the current lack of Hardcore talent in animation attempting stuff.
lol sorry trying to type and make sense and watch lewis black on comedy central at the same time XD
Overall comment: Good Job. Would be interested in watching more.
p.s. The reason why I decided to watch this was because on the page for the hammer bros song.... it just seemed like wtf? and kind of offensive so I watched. ^_^
