When I was in university, I met a guy whose grandfather was in a travelling circus (seriously) and this kid could do sleight of hand tricks, and I mean the real business. Funny thing was, even after he showed me what he was doing in slow motion, I still couldn't spot it when he was back at full speed.
What am I saying? You tell me its foamcore... you claim it's textured with a ballpoint pen and paint... then, I go back and look at the original photos. I don't see it. You have blindsided me with your skill. I've seen other buildings on these boards with more details, masterfully rendered and realized but, I have to say, in terms of capturing a mood, these are the best scratch-built buildings I've ever seen.
I take my hat off to you sir.
