I agree with you on that Kojima's art is superior, and I give you that Character models in LOS are not the strongest part of its art. But I don't see how can anyone just say that the art in the game is shitty when 90% of 3d games has worse looking and less imaginative environments, plus the game has a lot of texture variety.
Too bad that the ingame stuff is worse than the artwork i chose for LoS that's why i bolded "at best"... the previous artwork is sure more appealing than this
also Kojima's artworks are well transported in the games within the possibilities of the genre (2d sidescroller)
No game looks like Kojima's paintings, and it would look amazing if translated properly into a game, better than LOS. But LOS is currently a better effort (with its own art direction) , than previous 3D Castlevania with their's.
