Gun-wounded cake 3D- work in progress

My next independent art project is based on the theme of food! Instead of drawing this project out on paper, I plan on making a 3D sculpture. The issue I am addressing to is teen gun violence and deaths. While researching, I was really moved by the horrible massacre at Columbine high school, when many innocent students and teachers were killed and injured by two students armed with guns. I wanted to dedicate this project to the columbine massacre, so I decided to make a 3D sculpture of a angelic white cake pierced with many gun wounds. But the issuesalso refers to teen gun violence and deaths in general. A white cake is a representation of innocent life and gun holes around the cake is what wounding an innocent life. The cake will be made of salt-dough, white paint, caulk, and found objects for other decorations. The cake will be life size and will look very much like a realistic cake
