Marsh Shaman Demigod

Create a vertical dark fantasy oil-painting illustration of a towering marsh shaman-warrior striding forward through shallow swamp water at sunrise. The central figure is a muscular, mud-streaked, gray-tan skinned humanoid demigod with a grim shadowed face, long wild white hair and beard blowing across his chest, and two tall curved black horns rising from a dark ceremonial headpiece. He wears a ragged cloak made of reeds, straw, feathers, and swamp grasses that spreads over his shoulders like a huge mantle, plus layered primitive wrappings, belts, dangling beads, bones, shells, and talismans around his waist and arms. In his left hand he carries one very tall rough wooden staff topped with bundled reeds, cords, thorns, and a small circular bronze disk ornament; in his right hand he loosely grips the horned skull head of a dark animal companion or pelt hanging beside him. The environment is a dense wetland filled with tall brown reeds and cattails in the foreground and background, reflective muddy water around his knees, splashes around his advancing foot, and a pale blue-gray sky. Place a huge glowing white sun directly behind his head, forming a halo with faint thin geometric crosshair circles and lines. Add a small flock of exactly 7 white birds in the right sky, with a few tiny distant bird silhouettes. Use an epic mythological mood, high detail, painterly brushwork, muted ochres, browns, bone white, gray-blue sky, dramatic backlighting, atmospheric haze, intricate texture in reeds and wet fur, full-body low-angle composition, centered heroic pose, no text, no border, no modern objects.
