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 Longspear, and he is a young wildling. His armour are bits taken from the Nightwatch guards, and it doesnt quite fit him too well.
Illustrations for card games like this always have short deadlines, and are supposed to be viewed on a smaller scale than here.
