Personally I would lean more to a turn based approach than a winner, at least from a labelling it perspective, only because it may be a little discouraging for someone not to “win” as it were, especially as it may have been a week where they were, personally, really challenged to make what they made, and it could be their best work yet.
That said a little competition can be a healthy thing, but because your creations are all so personal and everyone will have varying skills/experience it doesn’t feel like the playing field is particularly even, you could always use the “poll” option in your topic and put it to the masses for consideration?
In my opinion though, based on the quality of all the work being done here, everyone is winning every week - I really enjoy seeing what you’re all making. Well done and keep it going
