DEMON & GOLD SLIME
Pencil, ink, and colored pencil on lined notebook paper. The game sprites, Phantasy Star Gaiden logo, and text were added later with the GIMP art program. I made these for a Phantasy Star monster redesign challenge at the Phantasy Star Cave forums.
Here I've converted my redesigned Gold Slime illustration into sprites for the four different slime variants in the Phantasy Star Gaiden game (purple = Slime, red = RSlime, green = PSlime, yellow/orange = GSlime).
