The production value, the quality of work, voice acting, character design, etc. Everything is so professionally executed that I question why this isn't being pitched to a big wig executive to air on television. This is something I could see on Spike TV, or Adult Swim.
The quality is extremely good, I'm wondering if you even used Flash to make it! Or is it Toon Boom? I must know! Regardless, this is excellent work. And very entertaining.
