I use the models for shadows and perspective. All the astronauts in their space suits look different to me. Different Apollo missions had different equipment. Individual astronauts looked different in their suits. People were different heights.
People wear suits and walk differently.
I've got an incredible model of the lunar module. It's as good as any I've ever seen. I had it built by a friend over in Sharpsburg, Georgia. I've got an other friend in Canada that's building me a Surveyor model. I've had space artists talk with me and say that they have.
