XIV doesn't need a drastic improvement on models, it mostly needs better shaders and textures. Just look at how much the visuals improved with better lighting. It would be great if they went for a style that attempted to mimic Ogura's coloring. It would suit the game much better and it would be easier to achieve than the more realistic shading they are trying to do now, especially when they are making so many characters.
Zarina is a great looking character by the way, I'd only delete that ugly ninja and replace him with Marco.
