UFC legend, big-talking tough guy and all-round king of controversy Conor McGregor knows a thing or two about tattoos. The Irishman is practically covered in them and would doubtless be impressed if he ever saw this version of himself rendered on a fan's lower leg. Given his gift for self-promotion, and his habit of doing nice things for his fans when he meets them, he'd probably fly them out for a fight, with ringside tickets!
When you're getting a tattoo of anybody known for their macho image, or their fighting ability, the key is to make sure they look as mean and moody on your skin as they do in the ring. Shaded, black and white images are a good way to go about achieving the effect, and the artist has done a good job of capturing McGregor's withering stare, which has intimidated many an opponent from across the ring.
