There's another four files available http://planetelderscrolls.gamespy.com/View.php?view=OblivionMods.Detail&id=5794.
Thanks JdeRau, didnt' know about those ones..
Damn, http://planetelderscrolls.gamespy.com/fms/Image.php?id=87184 and http://planetelderscrolls.gamespy.com/fms/Image.php?id=87183 screenshots look amazing.. The tonality of colors, truly "earthly".. What a fantastic job!
@ AmpolX: can you please tell me what replacer is the first link from? (Second is Jerall I guess, just downloaded!)
@ Anithinks: Mtgr's Textures definitely deserve mention.. Very well done and covers stuff not touched by others.
@ dmxdex2020: "better" in something visual is highly subjective.. All replacers discussed so far are high quality jobs.
I would add http://tesnexus.com/downloads/file.php?id=18677 - an extensive work, definitely superior over Vanilla but with same memory usage.
Also, http://tesnexus.com/downloads/file.php?id=18430 with http://tesnexus.com/downloads/file.php?id=18429
And regardless of how you replace textures, don't forget to get these must-haves:
http://tesnexus.com/downloads/file.php?id=16513 (all of them, but for Bruma you may consider http://tesnexus.com/downloads/file.php?id=26625 which I personally find superior to BC's one)
http://tesnexus.com/downloads/file.php?id=19370
http://tesnexus.com/downloads/file.php?id=18305 awesome complete weather overhaul with improved weather textures
http://tesnexus.com/downloads/file.php?id=34199 Lets you see outside windows!
http://tesnexus.com/downloads/file.php?id=19628
For a new experience, you may also experiment with http://tesnexus.com/downloads/file.php?id=30054 visual effects.
Enjoy

Edit: for terrain there's a very good Hi-Res replacer called http://tesnexus.com/downloads/file.php?id=15245
