That wave of hate where you're so sick of looking at character designs, painting the same location over and over again for 3 shots, fixing your previous frames, you wanna smash your tablet and never do animation again....
I think my sister (who does 2d anim as well) could totally relate to this XD Though when animating I'm pretty sure that agony of fixing the previous frames and wanting to give up anim forever is prevalent through all animators regardless of medium XD
And then it looks so amazing when you're done you don't mind taking on the next one XD
did you speed up that shake in the final?
Totally agree and yes I did : D
