ID: A 5-color pixel art illustration of the sonic OC Maimy, by artist Z-T00N. Maimy is a robotic sonic character in its typical style, similar to Amy Rose as a robot, with swept back spiky hair and cartoonish proportions with a huge head. She's got spiky triangular ears and wears a band with a bow on her head, a long simple dress over what looks like a buttoned-up shirt and big cartoony boots. She has big triangular forearms with three big robot fingers poking out from their base. She's smiling wide with huge wide open eyes, and is in a power pose swinging around her huge spiked ball from its chains, as if ready to hit someone or something with it.
The drawing uses bright teal/green and cyan, bright orange, strong purple and dark violet colors and mixes them with careful use of dithered screentones for an illusion of many different colors with careful shading and highlights.
