Enorme dragón negro sobrevolando una ciudad valyria en ruinas

Photorealistic digital painting, Balerion the Black Dread, the largest dragon to ever live, soaring over the Valyrian continent under a harsh midday sun; scales so black they absorb all light, casting a shadow wide enough to swallow entire cities below; red-black wing membranes backlit by the noon sun creating a terrifying stained-glass effect of deep crimson veining through black leather; skull the size of a castle gatehouse, teeth like broadswords yellowed with centuries of fire, eyes burning dark amber-red like dying coals; flame so hot it glows pale blue-white at its core before becoming a column of black smoke visible for a hundred miles; the dragon's sheer mass warping the air around it with heat distortion, scorch trails left in the earth far below, the Fourteen Flames of Old Valyria erupting in the background, ancient stone cities reduced to glass and ash beneath him, midday sky partially eclipsed by his wingspan, sunlight catching the oily iridescent shimmer of obsidian scales at extreme close range, ground troops the size of insects fleeing in every direction; rendered with intricate details, ultra-sharp focus, and volumetric lighting to convey epic scale and grandeur, 8k resolution, masterpiece quality, ultra-detailed, realistic, photorealistic, 16:9 aspect ratio.
