The real test about art is - can it be really easily reproduced?
If it can't be reproduced easily it is art that costs a lot.
It could take someone years to figure out the correct inks and paper I use.
Salvador Dali spent years trying to figure out how Vermeer painted.
Scientists actually dissect Rembrands with x-ray.
Well here's the truth, every artist has a secret ingredient they have figured out, I know I have secret ingredients for my drawings and no one else will ever be able to do anything even close to what I do. It's just a sacred combination of ideas and execution.
Same thing with Salvador Dali. His jewels will be hard to reproduce without actually looking like Salvador Dali.
My point is, there's stars exploding in the universe. There are black holes with mysteries beyond imagination, and there's art that could never be made again.
