ok so i LOVE thsi wall, everything, the texture the text, the composition and the colors, but theres just one thing that throws me off: the lack of shadow on his face makes hims seem disfigured, i think you should just make the shadow and then make it slightly darker or play with colors, wahtever just to imply that there is a shadow there.
sorry to blab your ears off 8d, but anyways really really great job!
