If these are in game renders, than there is no raytracing. Raytracing is a very computationally expensive technique, so it wouldn't make sense to use it on a realtime system. To me, it looks like they have somewhat clean and stylized textures on the characters faces. Probably done by some hand painting in photoshop, but based on photo textures.

I don't see what you mean by cell shaded. What I think it is, is very harsh contrasts between warm and cool lights. This gives the shot a dramatic
look to it.

Hope this helps, and good luck figuring out your own style!
