I know it's a bit early to be carving pumpkins but I wanted to practice before trying something more difficult.
I've got a few more planned already, but I'd still like to hear suggestions. :)

Weclock wearing a gas mask.

wow that's an awesome pumpkin.

Well it does have to be something that will work good in just black and white (or black and orange I should say). Unfortunately the wizball just looks too messy.

Hmm, how about carving jack o lanterns onto an otherwise normal pumpkin?

Wizard rocking out?
Sure, why not? Heavy metal often use fantasy references, so why not the other way around?
Oh, yeah... suggestion: a banjo and its human?

Indeed. Holy wow...
How about Hostile Waters' skull?

YES!!!
[EDIT] Also, this could look great on a pumpkin: http://www.free-desktop-wallpaper-download.com/data/media/44/ut1_chrome.jpg
Maybe without the outer ring.

Well, it just so happens that's the one I was working on. :)

Oh god, it starts again. Phalanx banjo man was better tho.

Wow. Great work. :D

Yay! That looks great! Plus, apparently I'm psychic :-O

And now the last one until I get a new pumpkin. :)

this is absolutely brilliant
