Hi @donnadavisart. Thanks for making my day!
I symphatize with your difficulty on photoshop, which is the only medium I mostly returned to these days from my failed attempts in other areas, such as watercolor, or any other traditional medium for that matter.

To answer your question, I once heard that concept artists talked about how they had raved about the trending of animating concept art as the next hype. Apparently it did not stick for long as it defeated its purpose in terms of idea limitation and speed practicality. But for animating fine art, I can see it is possible as long as it being just one of the forms of its expression. In my understanding, people are still making more still sculptures than moving ones. Because for me personally, still forms offer more mysteries and uncertainties, which consequently gain more fascination and interesting interpretations.

I'm not sure I answered your question correctly. But if you really want to see an animated fine art paintings as a movie, I highly recommend this:
