animation needs more anticipation and exaggeration, like there should be more frames leading up to mosquito-dude swallowing, as well as more frames between 321 and 322 showing the leg going all the way down. Also animating in 24fps instead of 12 would make the animation smoother, (although I recommend leaving the idle animations in 12). Also why doesn't your blinking animation doesn't go all the way down?

Quite like the sound design though
