Its still bloody awesome! Ive only ever carved one. It turned out ok, but its nowhere near as elaborate as that... It was an image of Holi's sons teddy bear that he loves. I will put the pic up on my DA. Hopefully when I am in the US I can do pumpkins every year. They arent that popular in the UK.
Your pumpkins should do well in that cool climate. The only downside to doing pumpkins in the South is that the weather isn't very friendly. Heat and insects are the pumpkin's mortal enemies. I try to keep it indoors during the day in an icebox or refrigerator.
