Thanks. Where I think I went wrong with it was to say; I'm a writer not a visual artist. I can do a bit of creative photoshopping but it's not really my talent.

Thanks. Where I think I went wrong with it was to say; I'm a writer not a visual artist. I can do a bit of creative photoshopping but it's not really my talent. So why not use the tools available? That will free me up to spend more time on the bit I'm good at. It seems logical but it ignores a holistic aesthetic that, as you say, is incongruous. A good AI image is worse for the overall product than an authentic but awful bit of amateur art, or even a hastily chosen stock image.
