|Note how the stonework is not a uniform colour. The black undercoat just shows through in places. The brush was run down the door planks, then the framing, leaving the black in the joints. Instant weathering. Note also that the door looks as if it could be opened. I make a point of adding a fine black line round the edge of any closed door or opening panel. This goes for rolling stock, vehicles, structures etc. I use a 01, or 02, Staedtler pigment liner. A couple of touches of black on the hinges and that was about it. Note the little tufts of fake fur grass.
