That looks fantastic! Gotta love the Part 7 Jason. Have you thought about making the ribs protrude from the stomach/guts area? I sold my Part 7 a year or so ago and I thought about redoing it and making the ribcage 3 dimensional.
The ribs do protrude some and have some deep gaps, but these are from a mold of another artist so I can't change these. They are great though. Some day I plan on doing the end scene wear he has most of his clothes burnt off and you can see a lot more flesh and ribs. I could do a display only even more weathered and accurate. But for a costume I try to keep them wearable yet still look awesome and not fall apart. I do a lot of these as they are the most requested costume by far. Also the the hardest and most time consuming to do, and the least comfortable to wear long.
