Hello!
Thank you for the offer, unfortunately I'm personally not a fan of Gen AI so I'm mainly focusing on 100% Human Made projects.
I do realize for a visual novel that's a lot of work and if you're trying to get a feel for what people think of the story that might not be the best invesment of time/money, however if you make the switch to Human Made art at some point down the line feel free to reach out!
Best of luck!
