The photo on the left – I put down some base colors. Looking at that I decided that a white shirt would not have remained white very long with a guy pulling coke. In fact .. his shirt could probably well have been unbleached muslin or something similar.
I ‘yellowed’ his shirt some then. Finally added shadow to him and his clothes. Next is highlights. I’m thinking the suspenders should be red. My friend Stan suggested the shoes should be brown. I agree .. work boots probably were just worn brown leather. I doubt he spent any time with polish .. although that helps preserve the leather.
