I mean, it could be a manual photoshop job.
It could, but the double spiral in the shell indicates AI to me. Snail shells don’t grow like that. If it was a manual job, they would have used a picture of a real shell.
Edit: plus the cat head looks weird where it connects to the head, and the markings don’t look right to me.
Even cnailshells would have to adhere to the basic laws of conchology though
