Sure but I'm asking why GR2 is a technical showcase.
Crisp clean shadows, good texture filtering, attractive lighting response on metals, goo, glass, brick and so on, parallax occlusion mapping, dense and varied particle animations, heavy destruction and physics objects in battle, animated cloth, clouds blowing through the sky islands (or sky islands floating through the clouds) I need to see the clouds more clearly but there appears to be a nice sense of depth.
GR2's art style is unique, even amongst cel/toon shaded games and there's plenty of subtle detail I think could be presented even more clearly to the press, watching and playing HDR source+display demos.
