For the shell I carved pink insulation foam and covered it in paper mache and spackle. Then I sanded it smooth and put a high gloss spray paint on. For the barrel, I used PVC pipe, craft foam, and clay. The claws are made of wood and plastic.
so wonderful pictures!! I love Emiri's Cosplay and your photos. They have a great atmosphere and reflex that Valve-Feeling XD The Portal-Gun looks awesome, too! Tell Emiri, that she is one of the bestes Chell-Cosplayers I've ever seen :3
