Leaping Silhouette Between Two Portals AI Image Prompt

Vertical composition 3:4, photorealistic cinematic concept art. High in the clouds, two colossal portals stand apart on the left and right, widely spaced, enormous in scale, with a tiny figure beneath them, emphasizing a dramatic size contrast. The sea of clouds occupies only the bottom quarter, while the cold deep blue sky above is vast. Slight low-angle wide shot. The external environment is dim and deep, with a cold deep blue sky. The cloud sea surface near the horizon on the left has a warm orange glow gradient, while the right side is cooler and darker, with uneven light distribution and no large uniformly bright areas. The light and shadow inside and outside are sharply separated, creating a strong sense of spatial isolation. The portals are elongated ellipses with soft, irregular contours. The frames are made of naturally weathered rock, extremely thin like shells, with rough textures retaining three-dimensionality. The edges gradually thin out and dissolve into mist, not resembling a door frame, as if the rock layer has naturally split to reveal another space. Vines sparsely cling to the rock surface. At the bottom of each portal, there is a floating rock platform of moderate thickness, extending only toward the front of the portal, with natural shadows underneath. Between the two platforms lies an abyss, with clouds churning below. On the left platform stands a tree, its slender trunk clinging to the rock frame and climbing upward; the canopy droops from the upper left into the portal, with layered branches and leaves like a curtain covering about one-third of the left portal. Through the gaps in the leaves, a city inside the portal is glimpsed. Inside the left portal — a near-future sci-fi city: In the foreground, a small amount of low greenery extends to the portal; in the midground, sky corridors and streamlined elevated roads span across; in the background, streamlined skyscrapers tower into the sky. The foreground is open and uncrowded, while the distant buildings rapidly shrink and converge into a warm thin mist, creating strong perspective depth. Glass curtain walls reflect a gentle warm glow, and the atmosphere inside is soft, warm, not glaring, full of vitality and hope. Inside the right portal — a vast cosmos: Bright orange-red nebula regions spread, interweaving with deep blue. A faint nebula band curves from near to deep, guiding the eye. The nebula transitions from dense and saturated in the foreground to dim in the distance, layering endlessly into the depths, where distant galaxies are softly out of focus, leaving only scattered starlight. It is brilliant, dreamlike, and full of the unknown. Centered between the two platforms, a tiny human silhouette hovers above the clouds, arms stretched forward, legs spread wide in a powerful leap, clothes trailing backward, jumping from left to right with dynamic tension. The left side of the body is slightly warm, the right side slightly cool. 35mm f/4 slight wide angle, focus locked on the portal interiors and the figure, cinematic color grading, volumetric light, atmospheric scattering, ARRI Alexa texture, fine film grain. Overall tone is deep and not overbright.
