2pt Interior - Evil Lab

we were charged with creating a 2 point perspective interior space with the theme: Evil Lair. We had to develop characters for it and somehow tell a story with the illustration of who owns the space.
so i chose to do an evil scientist's lab. it is owned by a mad/evil scientist who has dedicated his life towards finding and duplicating the human soul. in the process he ends up creating these weird creatures as he tries to create an artificial soul. Can you guess what these creatures eventually evolve into? >w>
