If someone sends me an NFT as a birthday present, I'm likely to feel insulted. A.I. slop masquerading as "creative design" for print-on-demand products is barely better, because why would I want a mug or T-shirt stained with slop? I think as the backlash against A.I. ripples through the market, there will be an interest in real objects made by real people, but right now, the illusion of affordability from A.I. is alluring as folks try to pinch pennies. Have you considered taking some video clips of your painting to share online? Different angles, different times of day, etc. could prevent accusations of it being generated video, but that remains a potential accusation.
