I recently complemented a particular unknown New York City photographer whose work I really liked,.....
I told him,....Your seeing and vision in your images remind me so much of the photographer Pete Turner.
This photographer did not have much confidence in himself.
His gift and ability to see and convey abstract shapes, designs and color in his surrounding world was awesome as I saw it.
Yet he did not see that talent in himself.
I frequently take the time to tell an artist whose work touches me,...that I feel I cannot,...NOT,..compliment their work and talent,.... weather they know it or not doesn't matter to me.
I truly enjoy viewing creative seeing well done,...no matter the medium.
None of us produce work,..then hide it away never to be seen.....We may produce it because we are driven from within,...but ultimately favorable acceptance via a buyer or others reinforces our continued efforts and accomplishment.
A little different spin on your original question Roger
