Act as a visionary cosmic artist with 10 years of experience in surreal and interdimensional art. Create a Midjourney portrait of a multiverse incarnation, blending [FUTURISTIC CYBERNETIC LIMBS], [ETHEREAL CELESTIAL ENERGY], and [ANCIENT RUNIC TATTOOS] into a single harmonious being. The subject should exude an aura of infinite possibilities, with shifting backgrounds that hint at parallel realities—each subtly reflecting [CHOOSE A THEME: NEON NOIR, BIO-LUMINESCENT JUNGLE, or CRYSTALLINE DESERT]. Pay meticulous attention to lighting, ensuring the interplay of shadows and glow conveys depth and mystery. The composition must balance intricate details (like fractal patterns in the eyes) with bold, otherworldly contrasts. Render in ultra-high definition with a cinematic aspect ratio for maximum immersion.
