A hyper-realistic full-body portrait in HD, 8K, captures a futuristic woman draped in the "Nebula Shroud," a full-body garment constructed from interlocking hexagonal patterns. These intricate shapes glow with bioluminescent hues, shifting fluidly between midnight blue, deep crimson, glowing cyan, and golden amber, creating a mesmerizing ripple of living energy. The outfit appears almost weightless, its edges dissolving into flickering trails of light, as if merging with her ethereal presence. Her porcelain skin radiates softly, contrasting with her sharp, shoulder-length jet-black hair, which cascades in glossy, structured waves. She stands poised against a surreal, chaotic background that pulses with dark, malevolent energy—a swirling gradient of deep violet and molten silver. Shadowy forms emerge from this chaotic void, taking the shape of demonic faces, clawed hands, and spectral entities. Their glowing red eyes pierce through the mist before the forms dissolve back into the swirling chaos, creating a haunting sense of unease. The lighting is cinematic and directional, casting fragmented shadows that enhance the crystalline textures of her attire while emphasizing the ominous figures behind her. The scene balances poised elegance with cosmic menace, blending avant-garde fashion with surreal horror in a composition filled with vivid detail, dramatic energy, and flawless execution.
