This is an illustration for Fantasy Flight Games collectible card game named A Game of Thrones, which is based on the world of best-selling author George R.R. Martins A Song of Ice & Fire.
The character is Tormund Giantsbane, and he is a big wildling. He is a loudmouthed braggart who always tells crazy stories about all the incredible things hes done. And yet hes strangely likeable, and his stories are a lot of fun to listen to.
Illustrations for card games like this always have short deadlines, and are supposed to be viewed on a smaller scale than here.
