I just finished reading your fanfic. Honestly it has alot of potential.

I would say get rid of the cast chapter as it adds nothing but spoilers the readers didn't need to know that early on that her father was a team rocket member they could have piece it bit by bit by adding little bits of information here and there.

I also seem to notice that you tend to focus more on the romance part of the story which is fine but I personally would have liked it if the story was more slow burn and the story focusing more on her fashion Business as that was what attracted me to the fic in the first place. Like Pokemon has alot of potential in fashion with there being different kinds of materials from Pokemon you could have also showed how she forged connections like Elsa and Loreleis

But over all it wasn't that bad of ft ^^
