Carving a skull pumpkin isn't terribly hard, but carving a great skull pumpkin is. This person has gone even further, they did it so well that they were able to keep the skin of the pumpkin where the teeth are. That's some carving skill right there! Awesome job.
When I am not carving pumpkins, I run a bulletproof vest company. BulletSafe Bulletproof Vests are the value leader in body armor. We are very popular with people like armored car operators and ATM repairmen.
