I can't remember which magazine it was in, but I remember an amazing, beautiful, model railway layout where the author made the point that he didn't like little people. Instead, he left hints of their existence - a bike leant against a wall and doors slightly ajar. Enough to suggest life without static people.
I'm not against model people (insert traditional note about not using running man figures) but I do appreciate the value of doors that aren't shut properly.
The Selly Oak arches are coming along and I've followed my own advice leaving a door in each arch ajar. Well, except for the one furthest from the camera, but there is a good reason for that which I'll come to another day.
I've also varied the design of the doors so it looks like the scene has evolved over time. It's not difficult to do when scratchbuilding, in fact it makes the job more interesting. I'm easily bored when repeating the same things!
All the above is in plastic sheet. Apart from the bricks, everything is scribed using an Olfa cutter with a few bits of plastic strip for embellishment.
