I’ve realized that I don’t like starting with washes or general block-ins.
I started to block in some shadow shapes with a thinned layer of umber, black and blue. I realized that I would just have to paint over this anyway with more accurate color and value. So why don’t I just go for the best detail I can get at the beginning? Of course I always refine my painting at least twice even if I start with accurate details at the beginning. In the end it all may work out the same but I just choose the process I like most.
