Yeah, the characters aren't truly consistent yet. We did what we could to make them mostly look the same. I might be adding inpainting to help address this. Right now you can just regenerate a couple times in editor and pick the most consistent ones.
I also like the slanted panels like in real manga. Right now you can resize the panels. I plan to add a custom layout thing on the select layout page. + allow folks to shape their panels into non-rectangular!
