Goal: Create an ultra-detailed fantasy triptych wallpaper made of exactly 3 tall vertical panels placed side by side with thin black dividers, each showing a different breathtaking world in cinematic realism.
Canvas: Tall portrait aspect ratio, about 9:16, high-resolution, immersive, sharp foreground and deep atmospheric perspective. No text, no logo, no watermark.
Layout: Divide the image into exactly 3 equal-width vertical scenes: left underwater, center mountain fantasy, right alien space landscape. Each panel should feel like its own epic environment while sharing the same luminous, magical, highly polished digital-art style.
Left panel — underwater civilization: Show a glowing blue ocean canyon with shafts of sunlight streaming down from the surface. Include exactly 2 large whales swimming near the top and mid-height, multiple translucent jellyfish of varying sizes, many small tropical fish, coral reefs, rocky arches, and a majestic submerged palace city with domes, towers, bridges, and warm lights. The color palette is turquoise, cyan, deep blue, and bioluminescent white.
Center panel — cherry blossom immortal mountain realm: Show an ancient East Asian pavilion balcony on a cliff above a sea of clouds at sunset. A lone robed woman with very long dark hair sits or kneels on the cliff edge, looking toward distant misty karst mountains and waterfalls. Include exactly 1 main character, exactly 1 large cherry blossom tree arching across the top with pink blossoms, drifting petals, ornate wooden roof eaves, lanterns, distant temples, and golden-pink sunset light. Use the mood of {argument name="fantasy mood" default="peaceful celestial wonder"}.
Right panel — alien ringed planet frontier: Show a snowy extraterrestrial mountain range under a star-filled sky with a giant ringed planet dominating the upper right. Include exactly 1 astronaut standing on a rocky snowy cliff in the foreground, looking out over an icy valley and glowing horizon. Include exactly 1 giant ringed planet, exactly 4 smaller moons or planets, a bright Milky Way band, and a few shooting stars. The palette is icy blue, violet, white, and cosmic indigo.
Visual style: Epic fantasy sci-fi concept art, photorealistic detail blended with painterly grandeur, dramatic lighting, volumetric rays, glowing highlights, crisp textures, high dynamic range, vertical poster composition, awe-inspiring scale. Emphasize {argument name="overall style" default="cinematic hyper-detailed digital painting"} and a unified dreamlike atmosphere.
Constraints: Use exactly 3 panels; keep the thin black vertical borders visible; do not add captions or typography; avoid extra human figures beyond the single woman in the center panel and the single astronaut in the right panel.
