This is most advanced use of AI I saw
nobody can say you are not an artist :)

the idea of making a story was good but probably depending on the complexity you could add more "before" pictures to make it a bit longer
like rendering the same girl intact and then when something happens in different poses and backgrounds.

Otherwise as single images your works looks perfect but there is no need for every picture to be that prefect :)

you also mentioned anytest for something
I think maybe that could be useful for me too to inpaint stuff on 3d images
So far I wanted to add footprints on the snow but it was not as successful as I wanted
Can you give some link what is it? or where to read more as google cant find anything
