If the competition is well defined and uses Kingdom judging criteria you already have a leg up on how your entry will be judged. The criteria tell you what to look for, the expected results and how values will be given to your work. Ultimately your judges give you points and a total value for your creation.
But more goes on during judging at a Calontir Kingdom level competition than evaluating an entry and ranking it among others. It's a way for a judge to mentor entrants, to encourage and teach them. It's also a way to encourage and teach a newer judge.
The Kingdom criteria for a craft limits a judge's biases focusing their attention on the specific qualities to consider and rate.
Calontir has a long history of coaching judges to use gentler tactics, especially at Queens Prize, where everyone is newer. Like asking you how you want to be judged? By a grade or just chatting. And including any critical points sandwiched amoung way more praiseworthy comments.
