If I hung any of these in my house and signed them with random names, no one would be able to tell that they weren’t organically made.

That really depends on how you create them. If it's a print then no one would care and it would likely fade out after a few decades. If it's painted on canvas then you've just made yourself a painting so might as well sign your own name :)
