I haven't seen any comments that I would classify as coaching. Instead they seem to be simple critiques.

"Overall, this image is good, but it could be great." https://keegan.regaind.io/p/whFZsOsRRfG4sRBGCDiA7g

"The blur and the subject together, so good. " https://keegan.regaind.io/p/HopS2XrnSmGhXiMg6AFoLA

"This is a solid image." https://keegan.regaind.io/p/USKPgJgfRE-h_n7rh2QnHg

"So simple, but so good" https://keegan.regaind.io/p/xbQHksWyRsOPWhW3hhs6RA

Don't get me wrong, I think this is pretty cool, but there is no real actionable feedback, so there unless you can guess as to what triggers the higher scores, there isn't much coaching, so much as "gaming" the AI.
