Create a portrait of a Nigerian man standing at 6 feet tall with a lean yet athletic build, exuding confidence and a fierce demeanor, his oily hair styled impeccably, framing his face with prominent facial features, a smooth dark brown skin tone, and piercing eyes, dressed in luxurious attire that accentuates his wealth, with a fit and tailored outfit, possibly a bespoke suit, adorned with elegant accessories such as a watch and cufflinks, posing in a powerful stance with a subtle smile, set against a sophisticated background that complements his rich and refined persona, with a full-body proportion that showcases his toned physique, conveying an aura of success and sophistication.
