Like many artists and authors I don't read reviews. I don't look at numbers.
Grading systems are for elementary school...and I left that behind a long time ago.
I do enjoy the random letter of appreciation. What artist/author wouldn't?
Reminds me of when I was eleven and wrote a fan letter to Norman Rockwell, a man who captured Americana better than anyone else ( IMO ) I sooooo wanted an autograph.
Alas, he thanked me for my adoration but declined. Such is the choice of the artist.
