My 60 year old ears don’t pick up things like that 
Having said that, we’re all too critical of our own tracks. We hear faults others would miss, and the discerning public wouldn’t even be listening for.
Same with my wife as a watercolour artist. She’s put thing sin the bin before now when I thought they should be in a gallery.
Enjoy it and don’t be too self critical is my motto. Life’s too short.
