Sindr is one of my favorite character in this game. It was rough to see what he had to go through.
When I was assigned to design a savage version of him on top of the existing rendering done by my art director Raf Grassetti, I tried my best to find the balance between desperation and rage. These two pieces were done with the constant help from Dela Longfish. Sindr looks amazing eventually in the game.
