Studio shoot

my set up (one of them)

Today I was in the studio all morning, generally making a mess but all for a good reason! I wanted to use a studio set-up to try and show progression of how sand builds up by objects and how this is the start of dunes. I was using a hair dryer to blow sand across the tray which was what caused so much mess, the studio actually ended up looking like a beach! Anyway, studio lighting is not my strong point by any stretch so any feedback on these composites is greatly appreciated!!!
