First do not put too many plastic bags and straws in the sculpture, unless you want to scare the hell of the facility staff while being fired. When I was called in to the pottery studio, a fire extinguisher was set at the doorway. The staff were truly worried about the kiln being on fire because of the strong smell emitted from the combusting plastics in the sculpture. In place of plastic I am going to experiment with natural substances. In the arms of my next figurine, I may put a cattail stem. It will be interesting.
Secondly do not spray varnish on the sculpture BEFORE photographing it. Now it glares so much that I can no longer play with the lighting to give more dramatic effect. I can still play with the background color, though. I am going to put a piece of black linen behind it to see if it will enhance the sculpture's color.
