Create a mechanical Supergirl-inspired portrait featuring a detailed face with global illumination and shadows rendered in octane. Capture an 8k ultra-sharp image, showcasing intricate metal ornaments with a cold color palette and touches of Egyptian detail. Emphasize highly intricate details and realistic lighting, similar to trends on CGSociety. Include glowing eyes and a direct gaze at the camera, with neon accents. The character should have mechanical limbs and visible blood vessels connected to tubes. Highlight the mechanical cervical connector attaching to her neck, with wires and cables linked to her head. Incorporate a creative and slightly abstract design approach, avoiding low-resolution images or any flaws in anatomy, ensuring high-quality output without artifacts, text errors, or unwanted elements. Make subtle creative adjustments while preserving the essence of the original concept.
