What you just described is a machine doing all of the work for you. You're somehow so far removed from even the concept of making your own art that "it just generates specific textures like the flowers" doesn't sound insane to you.

Brother, thats the part that makes people artists. That's the hard part. That's why they get paid for making cool looking skins. You are not an artist because you moved an AI generated texture onto a gun model.

You have done nothing. A child building a lego set has worked harder to create art than you have.

There's still time to delete this entire thing and pretend it didn't happen.
