3D animation in a blended style of Pixar and Tim Burton. Inside a human chest that looks like a dark, gothic cathedral. In the center are two lung characters, personified as sad, grey, cracking creatures with huge, expressive, tear-filled Pixar-style eyes. They are huddled together, trembling, and black, oily goo is seeping from the cracks on their bodies. The lighting is moody and dim, coming from above like light through a grimy cathedral window. Cinematic, emotional, and dark.
