This is a gif I came across on Facebook, it’s from one of my favourite animated TV Series Gravity Falls. I believe this is a rough set of 2D traditionally drawn frames that plan out the movement of the character Dipper Pines. This is a great example of a really well-done expression change, it’s a very detailed and informative plan, that includes, for example, where the light from the candle would hit Dipper’s body as he turns and it falls. Other than that it was a lot of exaggeration both in his features, the way he swings his body and drops the candle, perfectly matching his determined but awkward personality. I attached a gif of the final version of this movement to compare and is very close to the plan.
