Yep, Hourences is *definitely* a good source for level design.
Want proof? The 5 maps in UnrealTournament 2004's demo? He made 2 of them. (ONS-Torlan and DM-Rankin if you want specifics, they're also 2 of the most popular maps.)
I disagree with much he says, but only slightly.
Some other good tutorials of his are: http://help.hourences.com/tutorialsindex.htm <-- there. Most are based around Unrealengine (usually 3... which is the Gears of War version) though.
