Photoreal Thunderbird in a Cosmic Nebula

Photorealistic render of a colossal thunderbird soaring through a luminous nebula. The bird’s iridescent plumage shimmers with metallic greens, electric blues, and rich copper-gold tones; each feather shows microstructure, subtle sheen, and fine barbs. Electric blue and white sparks crackle along the wing quills, with a long, delicate trail of ionized air and faint lightning weaving behind as the wings sweep. The beak is curved and obsidian-black with a warm amber highlight; eyes burn like miniature suns. Behind it, a vibrant nebula swirls in pinks, magentas, purples, and electric blues, filled with star-dust and wispy gas clouds. Volumetric light bathes the scene, god rays piercing through the feathers, and a gentle fog adding depth. Perspective is slightly from below, looking up at the thunderbird in mid-flight, with a shallow depth of field so the creature remains in sharp focus against the cosmic backdrop. Mood is epic, mythic, and awe-inspiring; ultra-detailed textures, photorealistic lighting, high dynamic range, 8k quality.
