Thunderbird 3D Render in a Majestic Redwood Forest

Create a photorealistic 3D render of a colossal thunderbird with iridescent plumage in shades of sapphire, emerald, copper, and gold. The bird's wings are spread in a dramatic pose, talons clutching a moss-covered branch, set high in a cathedral-like redwood forest. Surrounding trees are towering ancient coast redwoods with thick moss, ferns, and fallen logs; soft morning fog curls between the roots. Use cinematic lighting with volumetric beams and god rays piercing the canopy, producing deep, cinematic shadows. Render with PBR materials, ray tracing, and global illumination for ultra-detailed textures on feathers, bark, and foliage. Camera angle is low and wide (around 24mm) to exaggerate scale, with shallow depth of field keeping the thunderbird in sharp focus while the forest softly blurs behind. Dawn light mixes warm amber with cool blue shadows, evoking mythic grandeur and natural majesty. Style: high fantasy realism, 3D CG render, ultra-detailed, cinematic color grading.
