I love so many artists especially Sugimori. I especially love his Misty's Tentacool underwater illustration
Atsuko Nishida's Bulbasaur is beautiful and has this incredible jelled-pastel look. She/he also did good with Misty's Psyduck in the gymleader collection. And when I look at Dark Dragonair by Karemaru Himeno, the name "Crystal Clair" comes to mind
In cell-shading I like Hisao Nakamura's Seedot, Sumiyoshi Kizuki's Abra,
Wow, I should make a list of my favorite card illustrations as an art report! I love this forum!
