A detailed 3D model of a majestic black raven, featuring clearly distinctive, intricately textured feathers with a subtle blue-grey iridescence, deep dark eyes, and a strong, glossy beak. Its sharp, scaly talons firmly grip a gnarled, weathered wooden branch, which curves gracefully downwards towards a base. The branch is adorned with patches of vibrant green moss and delicate lichens, all rendered with soft, realistic lighting and shadows, photorealistic octaine render, a branch made of solid wood with light spanish moss dangling from it. Make the bird's face and features as accurate to the image as possible.
