Kandoken has been a huge inspiration to me because of his vivid use of color and his strong line work. Also, a lot of his material is video game/cartoon/comic-related
Chamba has always been a big influence on me because of his crazy foreshortening (not really evidenced much here) and his crazy ability to use color (and photoshop!) so well. Also, he does video game fan art. That's pretty much a pre-requisite for this list…
This is an artist that I've only recently discovered but his skill and efficiency in photoshop are just as admirable as those who came before him. Also, video games…
Kizer layers his colors and values in a very loose but cohesive way. He has a very concise painterly technique that adds a certain energy to his art that is difficult to attain without getting to messy. In some ways his work is more of the same stuff (comics/cartoons/video games) done in his own style.
This guy's pretty good even though he's also relatively new to the scene so-to-speak. I particularly enjoy his ability to depict believably immersive environments as well as his playful use of color.
