I was originally going to carve outlines only, but then realized I needed to shave the skin off to get things to light up properly, so had to keep going.
I decided to carve the guy from Pan’s Labyrinth who has his eyes in his hands. I drew something out first, then taped it to the pumpkin and went over the important lines poking a blade into the pumpkin so that I had something resembling a perforated line where I needed to carve things.
