I feel to do a proper chamber cosplay you have have the open chest and then the fire placed ONTO that.... So here's the first sculpt of the chamber open chest. Much more work to do but I thought people should have an update...
On the left is the reference pic of him with no fire.

The fire sculpting will come later and be placed over this prosthetic.
