Darrell K Sweet is a major artist as far as fantasy coverart goes and did illustrations for Donaldson's T Covenant sereis as well as Asimov, Heinlein, and the Robert Jordan WOT covers.
He'll also be attending DragonCon 2005 in Atlant in the US Sep 2-5 very shortly in case you're in the neighbourhood, why I mentioned him.
Here's a link to other impressions of The Land incl. 13 large sized pics but does take a while to download and I'm using ADSL so be warned. There's some nice colour pics to start with and then some more basic B/W works. If any picture doesn't download just right click your mosue and select the option Show Picture to view it. There's also a nice link to a map of the land. http://theland.antgear.com/index.html
Here's another well known fan forum Kevin's Watch including fan art: http://www.kevinswatch.com/
Hope this helps....
