I've never been too pleased with the artwork from any of these books to tell you the truth. Well, path of daggers was decent but that's about it. But i gather that in Knife of dreams the cover is Perrin ( although is he also way too short and doesn't have redish hair.. and where the heck are the yellow eyes!?), and the Aielman is Gaul, and the woman at first i thought was berelain but then i read the first couple chapters a nd now i think that it might be galina. he soldier in the breastplate is some Ghealdean if i'm not mistake but i cant think of the name, and the dude with the black coat is obviously Neald the ash'a man.
