Here's the progress photos of how I made them.
The first pic shows the rough shapes, carved from .5mm styrofoam, 3/4" PVC pipe, and 1" pink insulation foam.
Second pic, the basic contouring of the foam pieces.
Third pic, scupted epoxy clay and more of the foam details, also coated it with resin.
Fourth pic, first coat of paint!
Last pic, done!
I don't have any progress pics of the dangly things on the guns. I simply made them out of hot glue, wire, and paint. Yes, hot glue.
