Giant Troll Gunslinger in the Wild West

Create a hyper-detailed, photorealistic 3D render of a towering troll in a Wild West town. The troll wears a worn brown leather duster, a cracked wide-brimmed cowboy hat, heavy boots with rusted spurs, and a belt with a colossal revolver holster. His green-gray skin is scarred and warty, with coarse hair and glowing amber eyes. He stands on a sunbaked wooden boardwalk in front of a saloon, with a dusty main street, tumbleweed, cacti, and horses tied to posts in the background. A massive wooden club with iron bands rests on one shoulder, signaling his access to brutal power. The scene is bathed in harsh noon sunlight with long shadows, cinematic lens flares, and subtle film grain. Materials should be physically-based (PBR): cracked leather, weathered wood, rusted metal, rough skin, and translucent subsurface scattering. Lighting features ray-traced shadows and high dynamic range; camera angle is slightly low to emphasize scale; depth of field softly blurs the background. Color palette: earthy browns, ochres, muted greens and blues. Render at 4K resolution with ultra-detailed skin pores, fabric fibers, and airborne dust motes enhancing the mood of a tense frontier moment.
