Wondering where the title 'Changing Moods' came from? Try focussing on one section of the painting at a time.
In your mind, divide the canvas into four squares. Then, look at a square at a time. The right-bottom square may evoke a particular feeling, whilst the top-left section may evoke another.
Wander through the landscape (that is, the painting) with your eyes, and see how it makes you feel as you take in each section.
Do you experience 'changing moods'?
