When is it (the painting) finished?

Does it stand in front of you and reject you? (it cries “don’t touch me”)

Does it have a life ot ite own? (if it does – you feel it, you can’t take your eyes of it)

Do you feel it has taken you on a long journey?

Do you feel it taught you a few lessons?

Do you feel exhausted?

If so….

It is probably finished.
