Create a hyper-realistic digital painting depicting a majestic, ancient tree whose bark seamlessly transforms into a sprawling, intricate city for the cinematic double-exposure portrait poster seamless blend. The colossal trunk of an elder tree dominates the frame, its deeply furrowed bark meticulously detailed. Within these organic valleys and ridges, an entire civilization flourishes, with tiny buildings, roads, and glowing windows nestled into the natural contours, appearing as if the tree itself is alive with urban life. The perspective is a close-up, revealing both the texture of the bark and the miniature city within. Details to include: microscopic streetlights illuminating winding 'roads' along the bark's fissures, a tiny, glowing clock tower emerging from a knot in the wood, miniature airships (like fireflies) navigating between 'branches' of the bark, a minuscule waterfall cascading down a crevice, powering a tiny, illuminated mill, and faint, glowing data streams flowing like rivers along the grain of the wood. The immediate environment around the tree is a surreal, slightly out-of-focus magical forest, with ethereal mists swirling at its base and gigantic, bioluminescent fungi providing soft, ambient light. The forest canopy above is a distant blur of deep emerald and sapphire, hinting at the immense scale of the tree. Dramatic, low-key lighting emanating from within the miniature city itself, casting long, intricate shadows across the bark-turned-landscape. There's a soft, diffused moonlight from above filtering through the forest, creating an enchanted and mysterious emotional intent. Rich, earthy tones of deep browns and greens for the tree, contrasted with warm, amber and sapphire glows from the city lights and bioluminescent elements. Awe-inspiring and magical, evoking wonder and a sense of discovery in a hidden, thriving world.
