Tadah! This is my pumpkin this year! I must say this is probably the best jack-o-lantern I've ever done. I was very nervous about how well it would work as you can probably imagine.
This took somewhere from 2-3 hours over the course of 2 nights including cleaning out the pumpkin. I created the pattern myself from a wallpaper of Vincent Valentine (thumbnail shown top left). I'll be putting up the pattern momentarily, but be forewarned, it is quite difficult.
Happy Halloween everyone!
The original image and Vincent Valentine belong to Square-Enix.
Pattern and carving by me.
totally freaked when I showed her this.
UPDATE: Pattern available here! [link]
