That's not art, it's image manipulation. Anyone can learn to do it and it doesn't require creative talent, you just need to know the steps to follow to achieve x y or z in photoshop with a pre-existing image.

Case in point: I can do this. My main education into image manipulation is a bootleg copy of Paintshop Pro I had on a disk decades ago. My current process is:

1. Google "online image editor free"
2. Click the first link.
3. Use the smudge tool or whatever the fuck.
