Mine would, of course, would be Better vampires. A new version is out now and it looks and improved an already incredible mod. I'm starting a new character and getting back into Skyrim again just because of this mod, and Vilja 3.0...it's yoo bad I can't turn her . My other favorite is the underworld dawnguard eyes which replaces the glowing eyes with the ones from the Underworld movies. I liked Bethesda eyes, as they were menacing and much better than Oblivion's.....but these are, in my opinion, much better. They're beautiful yet menacing at the same time.
