(It got third place.) When setting it up, placement of items was constrained partly, but not entirely, by the available light. Later I realized that I'd assumed, without thinking, that the cheesecake wedge should be placed with its wide end at the left, like an arrowhead pointing rightward. One reason was that the water glass was going at the right and would balance the bulk at the left. Another, perhaps, may have been that that's the way we read. Is the latter a good reason or not?
When your food has a shape that makes it directional, do you favor one direction of "pointing"?
