I agree that the UK cover is more elegant...however, I am so overwhelmingly pleased just to have the book in my possession that I'm not unduly distressed by the "Saruman" cover.
To be fair to J.J. Palencar, I don't think his cover is really all that bad by itself. I like the muted, almost monochromatic color scheme. But, yes, it's unfortunate that of all the characters he could've chosen to depict, he chose one that most superficially resembles a certain LOTR icon. I guess it was too much to ask for a depiction of, say, Linden Avery.
The problem is that the way the character is drawn, he is too much the generic wizard figure (old guy, white beard, white robe, staff) to be properly distinguished as a Forestal, if that is who it's supposed to be. There is nothing about his attire that is specific to a Forestal, but at least Palencar got the pupil-less eyes right.
D.K. Sweet's classic cover for The Illearth War still has the best depiction of a Forestal I've seen
