Looking for sketches, paintings, computer drawings etc.

Looking for...
Good guys-
Sorcerers (Mages, witches, warlocks, healers etc)
Rangers, like aragorn from LOTR but female preferebly, guys are ok
Elves
Warriors (Old fashioned, breastplates, leather, and chainmail kinda style).
Also, alien pepole (Like Draenai from WoW or the Avatar dudes.)

Bad guys-
Undead (Skeletons, zombies, etc.)
Orcs
Demons
Goblinis
other hellish creatures


I would like them to look realistic, but I don't want actual photographs.

Any help would be fantastic, also sites that have concept art like this.

Thanks!
Werewolves (and Shapeshifters), vampires, and other popular mythical creatures too :]
