Here is artist Neil Rodger's artist statement and I wholeheartedly agree: 
"I believe that pictures rarely benefit from commentary by the artist. In general I would say that while most good art has been extremely difficult and taxing in the making, it is a prerequisite of great art that this is not evident that it appears effortless or even inevitable." 
"Karoo Window II"
He was a great South African artist. His work is extremely soft and gentle. 
I just discovered his work today. He died last year.
