Has art jumped the shark after WWI?

They are mine.

When I paint I see two ways at once: a simplified whole and lots of abstract little pieces---the simplicity, and, as you say, the blob.

Wow twice.
I know you think you explained how you do what you do and to you it may seem simple. I think it's magic.
Exceptionally skilled people often think what they do is commonplace. I think it is one of the Dunning-Kruger effects. The highly competent underestimate their competence.
I only see two ways at once when I cross my eyes.
