Violet I really like your style... can you add to this with maybe dots with furniture/room setup in each one ending with the same R that you have here? He really wants some depiction of a room that is clean in his icon to go on his van.
Maybe use the same illustration style you did on the ducks - but outlines of furniture? a chair / a desk / a kitchen something????
I have given the same idea to a few others so know it is what they want.
