I'd like to be wrong, but my initial reaction is that this looks like it sucks. They recreated Spike's outfit too perfectly and I just think it looks weird if it's not animated.

doing anime >> live action just seems tough to pull off
seems a change in tone and visual style is usually a better option to fit live action then trying to be so matchy
