I’m going to go with Kizuki. Her original style is almost South Park-ish with really vibrant colors. A lot of the art in Rocket and Vending are my favorites of hers, but you can’t really go wrong with any.
Haha, was just about to comment this also… I have one of his artwork cards signed by him and a drawing he did back in 2015 signed too. Very awesome artist, good to see him livestreaming on the odd occasion as well!!!
There are so my great artists. One of my personal favorites is Ryo Ueda. I love the ex cards he did back in the day. An artist I have been really liking recently is Kouki Saitou. I love the style he’s taken on.
