Start with SkyUI, the Static Mesh Improvement Mod, and the 2k textures mod. After that, just go down the list of top mods on the nexus adding what you think would be interesting. You'll also need to get
BOSS to manage the order in which the mods are loaded, to help alleviate crashes and mods conflicting with each other. Just run BOSS again every time you make a change to which mods you're loading, before you start skyrim (but not individually for each mod, you can add 17 mods then run boss once then start skyrim).
Be forewarned that, unless you specifically override it in the install options, just about every body mesh mod will lead to complete nudity. Not just for yourself, but every bandit you loot, etc. Oh that's a nice suit of armor let me just take that off BOOM IT'S A WHAMADOODLE
