This was Martin Kovac's (NIGHT SHIFT) first structure model and the results look good to me!
There are two videos in this "series". The first (just under 20 min.) shows building a brick barn in 1:35 scale.
Martin cuts foam bricks with a wire cutter then weathers them. He also prints his own 3D roof tiles.

The second video (15.75 min) shows painting and weathering the barn and roof

I posted both together here and on the Painting & Weathering Techniques because the videos go together but fit under both headings.
Great video, and interesting technique.
