My first reaction was... "What the hell is that???"
The animation is really good, but this is kinda... pointless. I mean, you're gonna use it in another animation as you said, so it's more like an appetizer, I guess. It's ok.
But I agree with Satan. How did this get front paged? Not saying it's a shitty animation, but I think other works would deserve the daily second page more than this. I don't know.
