Shocking, this dude comes top or near top for cartoons for Christmas and Easter on Adobestock. Must have many many thousands of dls on these images.

agreed, these look like plagiarism but unfortunately, this wouldn't be tagged as similar as too much of image is different, much less as copying. each would need to be reported separately

I don't think it is just copying. Looking at the placement of the fur etc. IMHO they have got hold of the actual file, edited it and uploaded it as their own. Too much overlap in insignificant details that no one is going to copy exactly, if anything they would change them to avoid detection.

Also looking at the rest of their portfolio there are some images much better quality than the rest of it. Almost all of these images seem to be chopped around versions of these images of Santa and his reindeer.
