I can't tell if the animation was done on cels or digitally. Either way, bravo.
What I love most about the art is how the outlines have this chalk like texture, yet they house the basic "calarts" form. It's like a statement. "See, this style can look so good if we try".
Not too simple but not too complex. Make it too simplistic and you get why the calarts style is bashed on. Make it too simple and there's no much left to set it apart from the rest.
But you did it oh so well. Once again, bravo.
