Just getting the outline of a large tattoo done is a process that can take several hours. Getting that outline filled in with black and white, or shading, adds several more hours onto that. When you go for a full color rendition with as much detail as this tattoo has, it might even require several sessions across a period of days. But when the result is this good, it's always worth it.
Rap icons don't come much bigger than Snoop Dogg. He's been at the top of the game for decades, worked with anybody who's anybody, and become a star who's transcended the genre to become mainstream. He may go by 'Snoop Lion' these days, but anybody who's been listening to his music for a long time will always remember him as the 'D-O-Double-G'. This tattoo representation of him is every bit as bright and colorful as the man himself.
