Save The Artist!
Please refrain from telling an artist that their work looks or sounds like somebody else's. This is the quickest way to kill creativity. Best to keep it to yourself.
Art comes from source, and source comes from the ether. When you subject an artist to comparison or criticism, you take away their ability to create authentically in a vacuum.
Protect the artist and let them be original, even if reminds you of somebody else. Every stroke of the artist's brush is theirs and it's original, regardless.
The internet and access to everything known to mankind is deeply impacting the artist's ability to create freely, so please refrain from interfering with the work and process of the artist.
Simply, protect the artist and watch them create magic!
