Jufufu x Yixuan realistic announcement (Patreon)

I'm working on making Jufufu's animation look realistic and honestly everything was going fine, but I have a problem with the eyes. Not all the textures that come with the model work well when switching to realistic, so I'm seeing what I can do. For some reason the background of the eye is red instead of white and it looks weird. I'm gonna try making the outline whiter or greener so it looks better. Honestly I don't like uploading animations with defects — I at least try to fix them. I already have the animation but I don't like how the eyes look
