excellent
That was excellently done. I have a huge respect for claymation. A huge huge huge respect. And more so for people who do it well. THis was beautifully crafted together with a funny storyline and smooth animation. Plus the voice overs were also well done.
I suppose my only critique is there are only two characters who stand out, the armless guy and the villian. Plus, like you said, the ending needed some work. You still did it well. I, personally, just wish you would have spent a bit more time on the ending than you did.
