A powerful, **(ultra-detailed, masterpiece close-up portrait:1.4)** of a handsome, menacing man in a smoky, opulent underground casino. His expression is one of cold, simmering rage and calculated intent, with **piercing, unnervingly calm eyes** that hint at past violence. He is wearing a **tailored, dark pinstripe suit with a blood-red silk tie**, subtly stained. A **gleaming, intricate silver knuckle-duster** is visible on his right hand, resting casually on a poker table scattered with chips and playing cards. The lighting is **dramatic, low-key, with harsh spotlights from above**, creating deep shadows and highlights on his sharp features. The background is a soft-focus blur of shadowy figures and neon lights. (High contrast, rich textures, 8K, crime boss aesthetic, psychological thriller, subtle blood spatter, intense visual impact.)
