From animating in a parchment style to just straight up animating on parchment (the modern equivalent at least), you really know how to go above and beyond when it comes to your creations.
I looked up the specific Pokémon seen in this animation, and wow, he must have had a lot of determination to fully evolve in such a short amount of time. The movement here is very fluid, and each character has been brought to life very well; for example, you can see the determination in the newly-evolved Dragapult's eyes, and the pride and hubris in the orange Pokémon's laugh (sorry, I haven't played Gen 8 yet). I *did* feel like the animation cut off a bit early at the end, although it's only a minor thing.
As for the sound design, I think the inclusion of sound effects from the Game Boy Pokémon games is a cute and fun way to emphasise what's happening in the animation, such as when Drakloak looks over at the blue Pokémon, or when he grows his cannons to become Dragapult. One sound effect I'm not so sure about is the one where it sounds like he's talking before firing his cannons; I don't know if that's a sound effect from one of the games, or whether it's supposed to be speech. It didn't distract from the animation much, though, so I won't be too harsh about it.
Overall, this is a really good animation, and done in a way you wouldn't normally expect. Kudos to you for trying something different!
