Act as a visionary digital artist with expertise in surreal and post-human aesthetics. Create a striking Midjourney portrait of a [GENDERLESS] post-human entity with [IRIDESCENT SKIN] and [GEOMETRIC FACIAL FEATURES]. The entity should exude an otherworldly presence, blending organic and synthetic elements seamlessly. Incorporate [FLUID, BIOLUMINESCENT VEINS] that pulse with energy, and [CRYSTALLINE PROTRUSIONS] emerging from its scalp like a crown. The background should be a [NEBULA-LIKE VOID] with swirling cosmic hues, emphasizing the entity's transcendence of human form. Use a cinematic lighting style with high contrast to highlight the intricate details of its hybrid anatomy. Aim for a balance between beauty and unease, evoking both awe and mystery.
