Nebula Over Alien Canyon Valley

Jagged obsidian peaks frame a winding river that mirrors the sky, guiding the eye toward a distant horizon where a molten sun meets calm water. A luminous planet hangs above the valley, suspended between towering rock formations that recede into hazy layers. The composition balances vertical cliffs against horizontal water, creating depth through atmospheric perspective. Vivid pink and cyan nebulae dominate the upper half, streaked with white starlight and shifting into warm orange at the horizon. Soft clouds catch the sunset glow while cool blue tones dominate the shadowed cliffs. The palette moves from fiery magenta through turquoise to deep indigo, evoking both cosmic scale and serene twilight. The scene merges epic fantasy landscape tradition with science-fiction celestial drama, emphasizing grandeur, stillness, and the meeting of terrestrial and interstellar realms.
