I will probably do that, but it's not what I wanted to do. See, I'm including some diecast model cars.
They aren't quite the right scale, slightly large. The figures would look better next to the cars if raised slightly by being on bases. It would look more like they look during a game, except instead of being on felt or whatever, they would be standing on a carefully designed and painted base.
Anyway, if I do it as you say, with pins, I can do it both ways, and take photos both ways.
I think it was said there's no rule against WIP shots.
Man I really need to get started on this.
