kawayoo illustrated many cards in the more recent expansions, as well as promotional artwork for HeartGold/SoulSilver and Unleashed. I love his painterly, dynamic style, and am happy to say that have every one of his cards as of right now! Until the next expansion...
Nidorino, Hippopotas, Walrein
The first cards illustrated by kawayoo! They're all pretty random, I must admit. But that Walrein art probably has some of the best lighting I've ever seen on a pokemon card.
Supreme Victors (holo)
A gorgeously colorful card, with fantastic shading as always! Although I can't say I ever recall Cynthia owning a Rayquaza. But who cares! xD
Arceus (dread plate), Luxray, Bronzor, Gastly
Another set of amazing cards from the Arceus expansion! All of them this time are very unique. I will refrain from making any inappropriate comments about that Arceus card.
Heart Gold & Soul Silver
Totodile, Croconaw, Feraligator
For the HGSS expansion, a different artist illustrated each starter line. Kawayoo got Totodile, and I think he did an excellent job! Totally one of the most badass Feraligators ever.
Zubat, Golbat, Crobat
Bats, yeaah! I think we should all take a moment of our lives to fully appreciate the raw beauty of Golbat.
