I've been really digging on West LA artist David Jien's work. Erratic Phenomena has a huge interview with him, and a good sampling of his work. His work resembles a cross between video game-like isometric perspective, graffiti and classic Chinese painting.
I'm really digging on his use of color and the flatness of the images in the context of the perspective. There's a self-limitation there that is comparable to chiptune artists and creators of overtly retro video games.
There's an obsessiveness to the hyper-compact detail that is really brought out by the use of pencil. It almost reminds me of Wolfli, but representational and not, well, crazy.
