This is a nice example of great 3-D carving. The carver did a few things here that I like. Note the pupil and Iris are deeper because those parts of your eye are darker. Also, I really like the nose. Pumpkins noses can be difficult because most people's nose protrudes from their face, but pumpkins won't let you accomplish this. Finally, I like the teeth. Lots of depth and shape were used there. Nice 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.
