Potatoes! Out of curiosity, are those little potatoes glued together so they don't tumble out? I imagine they are, but they're so well done that I can't tell and wanted to ask. <3 Good luck with your show!
Just a quick DIY hack you can do for lighting, any sheet of paper will act as a great diffuser when doing photography. You can even use different colors of paper to change the color temp of the light in question. It's simple and cheap and can save you loads of time post processing-wise. Happy shooting!
