Epic high-fantasy panoramic scene of a colossal ancient tree towering above and fused with an ornate city, its massive twisting roots and vines forming terraces, stairways and cathedral-like façades; elegant spires, arched gateways, turrets with oxidized copper roofs and intricate stone carvings cling to the trunk, tiny glowing windows and hanging lanterns hinting at life within. A winding turquoise river flows through the city, crossed by graceful stone bridges, surrounded by lush tropical vegetation and moss-covered rocks. Misty blue mountain ranges recede into the distance under soft golden morning light from the left, casting volumetric sunbeams and gentle shadows across the scene. Foreground framed by giant roots and broad leaves for depth, rich textures of bark, stone, tile and foliage, high detail, photorealistic painterly style, cinematic composition, dramatic atmospheric perspective, vivid emerald and teal palette balanced with warm stone tones, serene and awe-inspiring mood, ultra-detailed, 8k, sharp focus with subtle filmic grain.
