Realistic colour portrait tattoo of Thanos by Louis Santos in Leeds

Colour realism portrait is a treat for me to do, as I love doing portraits. realism is a style that has the importance of an image to look believable, and understanding light. 

A good way to understand light in my opinion is to draw realism. I thought I knew about realism and light, until I had a seminar with the master of black and grey tattoo, Carlos Torres. He really opened my eyes about how to understand shadow and value, studying realistic images. Thank you.
