I'm not the best judge of short stories since they're really not my thing. But I did enjoy this, sort of. The writing is good, even though I was left with more questions than answers when I'd finished. Maybe its too deep for me, I don't know.
But if I was to give the Master painter in this story a piece of advice (and who am I?) I'd say "beauty in art is knowing when to call it finished. "
There's such a thing as over beating egg whites.
Its only 30 pages and is free. Read it for yourself and see what you think. I have some more observations but it would be spoiler ridden to voice them.
