Jpv,
Great idea for a textured look. I'm definitely going that way...but in my own fashion. I believe O Scale and larger scales benefit from the materials you use in conveying what is modeled. I will still strive for the look you've shown, but prefer to use a gypsm derivative and cast the bricks/stones. The building will be attached to a base to avoid damage. Tedious work...but I've done it in 2004 with the war torn Iraqi Diorama (shown above) ..can't beat the look...downselecting and shaping bricks, then molding and placement of the bricks should occur over the following few weeks/months....will take a while till next update, but...I believe it will be "spot on".
