Ai images are good (especially if you prefer cartoon style images) but they tend to lack the human element if that makes sense.
I used AI for a while but its sometimes as much work getting the prompt right so it gives you exactly what you want as it is to search some stock libraries for a good match.

My stories tends to be story focused so an image that relates to the story gets preference.

Captures the story and character well and it's pretty danged hot, too.
