Don't reveal your secret that you created these arts using automated software because your input value is nothing if a software does everything for you, or atleast don't reveal it as I said.
This is a form/genre of art, known as generative art. Though, the end product maybe something that was generated by a software, I am the sole reason why the software knows how exactly to draw these giraffes. This is more like the "process as an art" concept. You can see a lot of similar artworks like cryptopunks and hashmasks that follow the similar
core approach while the processes might be different.
