Got to say I never went That detailed, but did draw a lot. I was a bit of an introvert. In the sixth grade I was put into a special class with several of us trouble makers, drawing. we learned prospective and scale. drawing mostly Roman architecture. Drawing was like my model building now, kept me sane. I drew more houses than anything else, hot rods of course. I was in high school in '57-'61. The birth of hot rods and rock and roll. Wanted to be an architect, didn't happen. Wanted to be a pilot, Navy, that didn't happen either. But still sketch architectural stuff. Went thru a CAD school when I was 52, did the mechanical and architectural courses. Know just enough about building to be dangerous.
I admire the detail you put into your sketches Glenn. You got a good eye, or two.
