I'm trying to improve my design and creativity with color. This uses the raw render out of Maya/Arnold and a Zdepth AOV to control a series of hue/sat adjustment layers in Photoshop which set the colors. I first saw this kind of approach used by Pascal Blanche in his Chris Foss/John Harris inspired spaceship paintings.
Design and mood wise, this draws heavily from the work of Alex Steven Martin, an illustrator who does beautiful neon tinged cyberpunk images. I highly recommend checking his work out.
