Not sure when a painting is done.  Used to know - when I was working with oils, pastels, etc - during the last two years or so - I almost always knew when I was done - and I stopped working as soon as I reached the point where I could see my painting - done.

But this is different - what I’m doing now.   It’s almost as if …… we become expert at something, complete the cycle, and start all over again - but one rung up the latter.

Now, instead of painting with pigment, I’m painting with light.
