Any criteria for the art or rules?
Like it should be only done in any way like in digital or canvas using some paints or any drawing materials? If it should be done on canvas, does size matter on the canvas?..
Is any form of art allowed?
Handsfree, Hand Paint, Photoshop, Digital, etc.
No, it's just for fun, not for any particular purpose, so there's no strict criteria. Anything artistic and image-based is OK. Even things like photos of a 3D print you made would be OK.
Since the judging is not totally in merit based, I think it is much better to know what are the judging criterias for the art, like what should we consider or to be included in our art to get more points from the judges.(suggestion only)
For consensus, I am going to try to neutrally judge how much the community likes the submission based on comments and merit. Similar to the Wikipedia idea of consensus-judging.
Can we make unli submission?
Yes, but probably there will be diminishing returns.
