I'm not sure if anyone else knows about this little gem, but I haven't seen any topics linking to it before. This is the website of Mark Jones, an artist who worked at Bethesda during the days of Daggerfall, Battlespire, Redguard, Morrowind and a few "TES Travels" games. As such his gallery contains artwork and information on each of them. He's worked on games besides The Elder Scrolls as well so perhaps you'll find some more of your favorites.
Thanks to Mark for such a gem of a site, and to Bethesda for such a great series.
