Cinematic Movie Poster, Colossal Vertical Composition, a Single

Cinematic movie poster, colossal vertical composition, a single majestic galactic panorama that dramatically fuses five radically different art styles colliding in perfect cinematic harmony

infinite cosmic nebula cathedral exploding outward:

• foreground: ancient biomechanical alien megastructure ruins floating in zero-g (H.R. Giger / biomechanical horror fused with hyper-detailed cyberpunk chrome and rust, viridescent bioluminescence)
• midground left: serene ethereal wash galaxy, cherry blossom nebulae in soft pastel pinks & indigos, golden crane silhouettes made of stardust, 
• midground right: brutalist retro-futurist 1980s synthwave cityscape megapolis suspended in space, massive neon grids, palm trees made of magenta cyan light tubes, chrome DeLorean-shaped starships, strong vapor-trail motion blur, cinematic lens flares 
• extreme edges & accents: hand-painted psychedelic 1960s poster art crackle-glaze texture overlays, dripping Day-Glo ultraviolet colors, Peter Max / Heinz Edelmann pop-art cosmic swirls bleeding into every border

Dramatic centerpiece lightning:
• titanic god-like electric blue-white plasma lightning storm arcing horizontally across the entire 2/3 height of the frame
• hundreds of branching Lichtenberg figures made of pure ionized starlight
• secondary violet & magenta sheet lightning blooming behind the galactic core
• god rays of searing white light piercing through every layer like celestial searchlights

Lighting & mood:
• heroic rim-lighting from a neutron hypergiant star on the left edge (deep crimson to gold gradient)
• cold volumetric nebula fog god-rays cutting through darkness
• strong chiaroscuro contrast, filmic teal-orange grade, subtle bloom & lens distortion
• overwhelming sense of cosmic awe + impending cataclysm 
• enormous metallic title sculpture floating in center, letters forged from neutronium & cracked obsidian, glowing molten white core, lightning arcing through every letter
• tagline in elegant cinematic micro-serif below, chrome with subtle chromatic
