I did try gathering images from Wikipedia via the WikipediaData function, deleting any that weren't 3-channel images to eliminate black-and-white photos and 4-channel icons, and extracting features (FeatureExtraction) to abstract an artist's "style". Then I compared each artist's style with the restyled image in question using FeatureDistance. This did produce a set of metrics that I had hoped would point to the restyled image's artist. The numbers did not identify the artist though. They were not even close enough to lead me to believe that further effort would produce better results.
I'll leave this challenge for someone else in the Community to attempt. : )
