Your sound design adds a lot to your animation by helping to support the narrative. The contrast in light, as well as the color palettes you use, is very complementary. There's great motion, with a lot of it stemming from animating on a combination of twos and ones, giving the experience of high fluidity. The variation in line thickness deepens the characters' dimensions and communicates style and attitude. The boiling line effect I see is really cool as well.
