Photoreal Leprechaun in a Tower

Ultra-detailed photorealistic scene of a diminutive leprechaun inside an ancient Irish stone tower. Moonlight pours through narrow slit windows, illuminating rough mortar walls and a dusty spiral staircase. The leprechaun wears a vivid green suit with a gold-buckle hat, a neatly trimmed beard, and twinkling eyes. He stands beside a wooden chest spilling gleaming gold coins, a shamrock pin on his lapel. Dust motes float in the amber-green glow. Moss creeps over damp stones; outside, rain taps the tower's stone. The composition is cinematic with high-detail textures: fabric, leather, metal buckles, stone, moss; warm magical mood, 4k, hyperrealistic lighting.
