First, this is not my work. But I have to say I enjoyed looking at it while touring layouts today in Santa Cruz as part of the BAGRS open houses.
There were 3 very nice layouts open today, but the one (er, two) that stood out for me was John LaBabra’s G and HO layouts. The level of detail and realism is inspiring.
First was the outdoor large scale, set on a 6 foot tall retaining wall and backed by another retaining wall with carved cliffs. This is a smallish layout with a simple loop, but it is extremely nicely detailed as you can see from the photos here:
Even more detailed and impressive is his HO line, just inside nearby:
