Meh, Vray only ever looks realistic when you see renders of buildings and interiors, because of the easy hard surfaces. A trait of max itself really. Mayas good for organics and max is good for structural. Really all it is is good lighting and shader use. However, every render I've ever seen of a character in Vray still looks 3D, regardless of how detailed the models/textures look.

Even if someone did achieve those same renders in Vray, it'd be much easier to achieve those renders in mental ray and Maya.
