Linda,
I was actually trying to be slightly serious

I did not address it to you alone, but to all members.
Those maxims seem to cover all the aspects of painting like the masters, so if we joined our common knowledge, here on the forum, we might be able to define to meaning of every single rule set up by Paxton.
Alex made a fine example with "backgrounds" I believe that it must be possible to define the maxims by words and examples if we put our minds to it.
I will attach an example that, in my understanding, illustrates "flow" - how one area flows into another.
"Beauty"should not be one single element in the portrait (the person) but should be supported by the way the the whole picture is painted.
I really look forward to a concentrated and serious attempt to solve this topic.
Happy New Year to all.
