Steve, do you paint a grey wash first or is the second image just a grey scale version of the final colored sketch? I like the clarity and consistency of your sketches!
The gray wash comes before the color layer(s). I was in too big a hurry on this one and prefer the gray stage. I even forgot to finish the Mexican flag and put the graffiti on the lighthouse, I see.
Always enjoy your work Steve, thanks for showing the process.
