A dark fantasy illustrative painting in the traditional mixed media style of gouache, acrylic, and colored pencil. Full-body shot of a futuristic female anime mecha character (CAST style) with yellow face, glowing green eyes, and short dark hair with robotic pointed ears, and long insectoid horns. She is wearing sleek, sharp yellow and dark grey mechanical armor plating. Large glowing neon-yellow cybernetic wings extend from her back, with a small round robotic drone floating nearby. She is dual-wielding matching futuristic sci-fi submachine guns, featuring a glowing neon-yellow top rail tube, a blocky metallic-grey frame, an oversized full-hand square trigger guard, a thick forward box magazine, and front-mounted rail accessories. Electricity arcs around her. The style uses dramatic chiaroscuro and atmospheric haze. In place of clean digital lines, the entire composition is rendered with visible brushstrokes and cross-hatching, featuring soft, smoke-like edges. The color palette is composed of deep, saturated jewel tones. A pronounced texture grain is visible across the final output.
