Jan Strnad's script called for a milk mustache on Bruce but DC strongly objected. That's why you see him wiping his mouth in the second panel of the layout. I've heard that Bruce Timm has a rule against showing Batman like this, mostly still in costume, but with his cowl down. It surprised me when I first heard about it but it makes sense now. It takes away from his mystique. Bruce Wayne's, not Bruce Timm's. Nothing could diminish Bruce Timm's mystique.
