Alex Wer aka The Pumpkin Geek is possibly the best pumpkin carver I've come across so far.
Following are some of his insane creations. Each pumpkin is painstakingly hand carved on a 'faux' pumpkin for an everlasting keepsake.It takes Wer between four to six hours to complete each piece.
He also does commissioned work so head over to The Pumpkin Geek for more info.
