Rules - The only rule is that your creation has to include some sort of pumpkin, gourd, squash or something of that ilk. If you want to incorporate 3D printed stuff, NFT's, coins, whatever, all the better! There will only be one entry per person (but this can include a bulk of items together (i.e. a 3 pumpkin set with a drawing next to it, for example).
Edit:
As for the rules, yes , it MUST be bitcoin related in some fashion. If its just some regular pumpkin, without any bitcoin anything connected to it, it does not qualify.
A bit pity that the rules of the contest were updated right after the submission date has passed

Literally says in the title BitcoinTalk BITCOIN pumpkin carving contest. It should have been obvious it needed to be bitcoin related based on the OP which says bitcoin in the title, has multiple examples of bitcoin carved pumpkins as well as what aoluain mentioned, that I mentioned this several other times throughout the contest.
Why people have to complain about a fun/free things, is beyond me. Did I set this up perfectly? No. This was my first time and a bit of a learning experience but I think overall everyone had fun with this. I mean I never expected over 80 entires!
Update on Poll: Ive reached out to Theymos and waiting to hear back for further instructions. Again, he offered to help add some provisions to the poll in which will make it more fair voting wise.
Those extra rules as quoted by Theynos to me 1) only Member+ votes will count, where copper membership does not on its own count as Member; and 2) users who haven't made a post in the year between the time of this post and 1 year ago will not be counted. I'll post the adjusted results at the end. In case of a tie in the end, the candidate who at that time has more total merit in the art contest thread will win.
So stay tuned everyone, well open voting here soon!
