heh, actually your first animation is good, I don't see any mistakes with the animation at all, and it's about Zero Pwning, so it's gotta be good ^^
The second pic looks awesome, although I'm not totally sure what characters are on it, it still looks awesome.
The second animation looks like another "endless combo" and it's very well done

Overall, I'm giving you a 15/10 because it's just so awesome

I'm thinking of getting rid of this avatar and putting that animation on a banner, I know how to do it, it's just a long and boring process lmfao
