I've been searching planet elderscrolls and a few other sites. No luck,
Not sure what you mean by that, since 99% of all the textures are on PES.
I recommend Mr. Swiveller for you. His work is great, and keeps the same mood of the original. (he's on PES)
In the
Graphics! thread, there is a http://www.gamesas.com/index.php?/topic/956115-graphics-to-those-asking-about-graphics-mods-start-here/page__view__findpost__p__13811799 (scroll down a bit)
You might also want to look at http://web.archive.org/web/20080514081136rn_1/ltm.ufrealms.net/textpacks/
You can also use Connary's older textures, which look great and are close to the original also. They can be found through the megaupload link in http://www.gamesas.com/index.php?/topic/1082054-connarys-retextures-gonne/page__view__findpost__p__15763006
Oh, and for armor/weapons textures, Darknut is your man.
Also check out the work of Alaisiagae. She has lots of little great texture replacers. (both of the modders are on PES)
