Throw it in the moat, nobody will notice ..
Having got the shade of my roof tile paper right, I painted the timber beams. For windows I used a dark grey and put 'leaded' widnow lines on. The overall effect has captured the look I wanted. I made the gates so they could be removed and replaced with two open ones.
The gatehouse done I then stuck tile paper onto the roofs of the other buildings. Having finished that I realised I hadn't added the chimneys, a minor modification for later.
