Highly detailed 3D model of Stribog, the Slavic god of wind, standing on a mountain peak in T-pose. He has long flowing silver hair and a beard, with billowing robes adorned with air and wind symbols. His eyes glow faintly, and gusts of wind swirl around him. The character should have a powerful, ancient appearance, emphasizing his connection to the elements. Use realistic textures and dynamic lighting to highlight the wind-blown fabric and his ethereal presence.
