Three Worlds Vertical Fantasy Triptych

A cinematic fantasy triptych in a tall vertical composition, divided into three equal vertical panels side by side with clean straight dividing borders and no text. Left panel: [an underwater Atlantis city with whales and glowing jellyfish]. A grand submerged fantasy city built into cliffs and arches beneath glowing turquoise-blue water, with volumetric beams of sunlight piercing from the surface. Coral reefs and rocky ledges frame the foreground, while ornate domed towers and bridges span the middle distance. Two large whales swim near the upper ocean, accompanied by small tropical fish and translucent bioluminescent jellyfish, with the largest jellyfish floating in the lower left foreground. Color palette: cyan, teal, and deep ocean blue. Center panel: [a cherry blossom mountain temple above clouds at sunset]. A serene East Asian mountain temple surrounded by blooming pink cherry blossoms at sunset. A dark wooden pavilion roof and balcony with hanging lanterns occupy the left foreground. A lone woman in a flowing white robe with long black hair sits on a cliff edge looking out over steep karst peaks, cloud seas, waterfalls, and distant pagodas. Cherry blossom branches arch across the top as delicate pink petals drift through the air. Color palette: warm peach, rose, lavender, and soft gold. Right panel: [an alien icy planet landscape with a ringed planet and astronaut]. A snowy alien mountain world beneath a starlit cosmic sky. A lone astronaut in a detailed spacesuit stands on a jagged snowy cliff in the lower foreground, looking out toward a frozen lake and distant mountains. Dominating the sky above is a massive blue ringed planet with visible diagonal rings, flanked by four smaller celestial moons, a glowing Milky Way band, and subtle shooting stars. Color palette: navy, icy blue, crisp white, and deep violet. Style: Hyper-detailed fantasy concept art, cinematic lighting, high dynamic range, sharp foreground textures, atmospheric depth, and luminous highlights, composed as a cohesive vertical wallpaper.
