Mechanical Supergirl portrait with a detailed face, showcasing global illumination, shadows, rendered in octane, in 8k resolution with ultra-sharp metal and intricate ornaments. Emphasizing cold colors and Egyptian-inspired details, the scene is enriched with realistic light, as seen in trending CGSociety artworks. Her glowing eyes face the camera, with neon elements highlighting her mechanical limbs. Blood vessels are connected to tubes, with a mechanical cervical structure attaching to her neck. Wires and cables are seen connecting to her head, adding to the complexity. Despite retaining a cartoonish essence, the design avoids low resolution pitfalls, maintaining high quality without distracting elements such as text, errors, and image artifacts. The overall composition is kept clear of NSFW elements and embodies a young, elf-like futuristic appearance.
