It sounds like we agree that we are our worst critic, my wife does QC on my work and thinks some of the stuff I am ready to drop in the scrap pile is just dandy, people that buy it love it, it isn't just right, but my wife saw it before it went away to scrap.
My later work is a vast improvement over "The early stuff", but still needs improvement.
I made a sign that said Fultz for a wedding present, I was on the 3rd revision of it and finially got what I thought was sa good sign. Vulcan the shop assistant cat liked it, Anita liked it, I thought it was good. Put it in the mail and Anita posted a pic on FB, one of her friends in England asked if the Z was supposed to be backwards....Looked at the pic and darned if the Z wasn't slanted wrong. Big OOPS. I quickly made another sign with a correct Z and sent it with apologies. The customer loved the unique sign ?! Well they got a 2fer-2 fer the price of 1.
