Thunderbound Wyvern in a Photoreal Storm

Photorealistic render of a wyvern perched on a jagged basalt cliff during a ferocious thunderstorm. The dragon-like creature has a lean, muscular body, two hind legs, a long tail, and expansive bat-like wings with tattered membranes. Its scales are dark emerald and midnight blue, slick with rain, with an iron-gray underbelly. The head is angular with a sharp beak, piercing amber eyes, and small horns along the skull. Rain pelts the creature; droplets bead and stream, wind whips the wing membranes into motion blur. The sky is a roiling mass of storm clouds, with bright forked lightning illuminating the scene and casting stark, high-contrast lighting on the wyvern and cliff. A storm-tossed sea roars below, with mist and spray swirling around the rock. The image is ultra-detailed, with volumetric lighting, realistic textures, wet reflections, and shallow depth of field to emphasize the wyvern. Cinematic, 8k-level realism.
