Sure, I'd appreciate suggestions. That's something I haven't thought about yet and I'm glad you mentioned it. Aside from adding additions to book 1, I also want to make the original animations smooth. Unfortunately, book 1 isn't up to date with that compared to the books 2, 3, and 4 so I always wanted to do that. I'm not sure if Mity will update those someday but until then I can add my variants. The original animations in book 1 aren't dynamic as in other books which means katara's other body parts don't move while in action. I did a little test before with the same style as in other books and it worked quite well. Mity did fantastic work with his art and I'll just give it a pedestal where it can stand.
I've made myself a project plan and will work from book 4 to 1 including the routes. Book 1 will take longer than the other ones thus I decided to work on it once everything is done. But I'll share the first version once I'm done with the slave route in book 4 to get feedback. I'm currently working on Eska and Desna which is going pretty nicely.
This is fanmade so all suggestions are pretty much welcome.
