I really liked Alola, but a couple of these designs blow me away: Wooloo and Corviknight. What I really love about Wooloo is that a lot of its charm is in its overworld animation, rolling around. That adds layers of life to both it and Galar. I'm hoping something similar happens with Corviknight.
There's so much foreshadowing around the Raven Pokémon. From Professor Magnolia's cane to the taxi service, it just feels important and epic already. I hope it's extremely hard to catch: limited location, rare appearance, tough battle, low catch rate. But once caught, I hope it allows us to Soar like in ORAS. That would be so awesome!
It's also very cool to me that James Turner, the first Westerner (Maybe first non-Japanese) to design Pokémon also happens to be British and also happens to be taking on the helm of Art Director for the first time with these games. This is sure to feel like a labor of love throughout. What a dream come true for this guy!
