• Positive Prompt:

  A cinematic, professional movie poster with a vertical 2:3 composition, titled 'The Obsidian Helix'. At the center, a colossal, glass-like obsidian supercell tornado looms majestically over a vast, cracked dark desert under a starless night sky. The twisting funnel is semi-translucent, glowing from within with trapped, branching magenta and violet lightning strikes that illuminate its crystalline structure. Swirling rings of iridescent atmospheric dust, shimmering teal particles, and cosmic debris orbit the helix. The foreground features highly detailed cracked desert earth, faintly reflecting the intense electric glow from above. The aesthetic is neo-noir, with high-contrast chiaroscuro lighting, deep obsidian shadows, and rich textures. At the bottom of the poster, the caption 'Nature's dark, electric sculpture.' is elegantly integrated in a clean, minimalist, ultra-thin sans-serif font with a faint, sharp magenta neon glow, perfectly centered and legible. Masterpiece, 8k resolution, professional graphic design, atmospheric and moody.
