quality issue?

The wood texture seems inconsistent here. Also the right handle seems smaller than the left one, even from this perspective it seems that it should be longer.

I'm wondering if those are generative AI assets (they do not look like generative AI) or if they are phone pictures (they look a lot like phone pictures).

For your wooden rolling pin, did you try to do a cutout, to isolate the device for a neutral background? These "shadow" lines, claimed as artefacts by @RALPH_L remind me of a less than perfect cutout trial. 

Took me awhile, but probably these "scuff" marks.

Rendering errors.
