Art isn't about the craft of the image (that's part of it, but that's craft, not art). So AI's won't get there, unless they do actually develop a soul. Even then, I think their art would be for other AI's, and that humans wouldn't necessarily get much out of it, except may some insight into our hypothetical souled AI.

So in your human and animal art, maybe look for the soul you put in there, if you're concerned your craft isn't where you want it to be. I like the grace of the kneeling woman on the dock, and the easy relationship of the woman with her pony. Also, the red panda(?) who's looking back at you more than letting itself be looked at...

(I do also like the street scenes, and the especially the dramatic lighting! And the fuzzy light on the hanging fruit :-)
