I'm just saying it doesn't really suit his style well to go with the quasi realism. You start to see cracks form with stuff and it breaks the suspension of disbelief. I know they chose to go that route but I'm saying in my opinion it just doesn't look right especially since there are other games that have used his style before.
Renderers are going to depict realistic light and shadows differently than going for cel shaded look.
Guilty gear used an array of texture techniques and shaders to pull off the 2d look on the same engine
