Cut the Face
Decide which parts of the facial features will be removed completely and those that will be left behind as 3-dimensional details. Use a carving tool or knife to cut out the areas that will be removed. For the eyes, remove the whites but leave the iris intact. .
Use a razor blade or electric rotary tool to shave the 3-dimensional details; the irises of the eyes, the nose and teeth. Shave about a quarter of an inch from these areas leaving at least one half the thickness of the pumpkin’s wall. This will ensure that these pieces are strong enough to stand on their own. If you make a mistake and a piece breaks off, use a toothpick to reattach it.
