Righto, that's it for now. I've got some more installed but these just rock honestly. Sad thing is that Steam sorta' loses the quality of my screenshots when I upload them, they look better ingame, but oh well.
Of course, feel free to add some more mods to the list.
Using no mod manager right now. There's one out, but it's not the classical manager you might know from Oblivion. But the Creation Kit isn't out yet, mods are fairly easy to install. Just drop them into your data folder, and get SKSE first (Script Extender, for complicated mods).
Like Serious HD retexture, it changes many of Skyrims low res textures to some high res ones, combine with Serious HD retexture for a better experience. Skyrim HD is still in development, but absolutely recommended.
One of my personal favourites. This one replaces the textures of faces from both male and female characters into high res ones, also included: Eyes, Lips and removes the blockiness of many characters faces.
