A friend said to me
“You captured his character. Don’t make another stroke”
I thought; ‘it needs more work’, but I stop. 
A picture can be completely ruined, and never recovered by one little stroke of color or line, which changes the image if the artist does not know WHEN  to stop and leave it alone.
Though this picture needs more work, I officially ‘leave it alone’.
Although sometimes, it may just be because of laziness.
Yikes!
