Artful Expression through Pumpkin Carving

In the spirit of Halloween I was looking at interesting pumpkin carving.  It is something I have only tried to  carve a pumpkin a hand full of times but last year I impressed myself a little with my Jack Skellington.

I have yet to try something terribly difficult this year, I have stopped at drawing on one with a sharpie this year.  But I am hoping to follow some of the stuff I found online.
