Audio was good. The art style and colourings was all right, but the animation itself I felt was really dull. Within each scenes, the only thing I see are always 1)The characters mouths moving and/ro 2) Their eyes moving around. There's rarely any body movements, or facial expressions which makes all the characters look as bland as cut-out paper dolls instead of actual people, and the BG is no more different.
One example was the bus scene, where the dude pushes his head out of the windows. The glass shards would be flying out from the impact, instead of sliding down the side of the bus like pieces of cloth. And the guy in the purple jacket on the right should have a more stronger reaction to the sudden surprise.
