I want to say thanks for the pattern of Rob Zombie
I used the dremel carver for pumpkins on this.
The one thing I found easier, was to use an exacto knife and slice through the pattern.

When I shade, I do the same, sort of. First I run an exact-o knife down the lines, but I just use a small wood carving tool to pull the skin up. By using the exact-o knife first, I can get really nice lines.
