Wow Scott for a first timer this is looking awesome, great job on the buildings,
If I could make a small suggestion regarding the detail on the rebars which is a great idea using those paperclips,
Mostly the rebar for houses is made of a mesh of steel wires, if you know what i mean, jet this is no kritik just some advice that will bring more detail too your building.
put in a picture of what i mean.

Keep up this great build will be following this closely
