Thanks to everybody for the answers, I am always grateful for people who take the time to help us sad newbies. It is an AI-generated image and I believe that I did follow the guide to the letter - I guess I will have to regenerate it and look at a better method for upscaling it. My guess as to the artifacts is that I generated a jpg file and upscaled it t a png file will jpg to jpg next time.
"I will have to regenerate it and look at a better method for upscaling it."
Adobe's rules are absolutely clear on this point. You MUST NOT upscale it. If generating an AI, it has to be generated at the final size - and the AI must not be upscaling either.
Thanks for the response and I would agree 100% if this was a photograph of something that actually existed, but this is intended to be a representation of a surreal painting where blurry edges would be sort of expected?
No! Even as a surreal image, you should follow the guidelines. But there are not only blurry edges, but also compression artefacts. Why that is, is not understandable as your image is a png 😉 :
