D&D4e art
I've liked and disliked bits of the art in every edition of "Dungeons & Dragons," and I expect D&D4e to be no different, although the importance of the core rulebooks as something that most D20 players will refer to regularly can't be underestimated. The tone, from eccentric black-and-white art, to lush paintings, to spiky-haired and -armored characters, presents D&D's image to the outside world and helps recruit and define each generation of role-players.
I, for one, wouldn't mind seeing Erol Otus' weird monsters, Larry Elmore's well-proportioned people, and Claudio Pozas' clean lines in D&D4e. I think the core books should be generic fantasy, with a mix of epic heroism, low-powered gritty adventure, and fantastic creatures and magic. Specific worldbooks or sourcebooks can then take a game in one directon or another, from combat-heavy dungeon crawls, to steampunk exploration, to court intrigue.
Did anyone else notice that some of the sample art featured what might be the iconic four classes of the new edition? I know that's probably being discussed on numerous other threads, but a Dwarf Cleric, a human Wizard and Fighter or Paladin, and an Elf Rogue or Ranger is more promising in terms of iconic characters than the Tiefling on the cover of the new PHB...
