Connary's textures make a good base to build on.
Mixed textures is worth a look. http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=7492
Check out Vurts work also. Tree models and sky textures in particular. They're available on PES and Nexus.
Head models you'll be spoilt for choice, just depends what kind of a feel you want. If you're looking for really well detailed ones have a look on here for Mels head packs. If you want to freak her out ask for some better eyes versions of what she's done!
For clothing Canadian Ice is worth a look.
This is just off the top of my head.
