Try Guard Dialogue Overhaul. [http://skyrim.nexusmods.com/mods/23390] There were a lot of leftover sound files that Bethesda never put into the game. It makes the Guards less annoying and gives them a lot more to say. They also give you a lot of respect if you are a dragon slayer now.
Also, Project Reality. [http://skyrim.nexusmods.com/mods/17802] You don't need those fancy ENB injectors to get the full beauty of this mod. It is really just incredible to look at when you are in the mountains. I went to High Hrothgar on a clear day, no snow, blue skies. The view was stunning.
Lastly, the Bucklers Mod. [http://skyrim.nexusmods.com/mods/5315] If you want to use light armor but hate the shields and vanilla outfits, then this mod is a must. It gives you both light armor variants of heavy armors (same appearance, different stats), as well as Bucklers, smaller shields that aren't as bulky looking as the regular ones.
We obviously have similar aesthetic tastes. I already use
Project Reality too lol.
Bucklers sounds like a nice addition and I'm pretty excited about
Guard Dialogue Overhaul.
I'm sure you've heard of
Build Your Own Home. It's a little more interesting than the vanilla houses, and I like living in the woods so I can waylay travelers. I never do it, I just like knowing I can.
Realistic Ragdolls and Force is a classic carry over from
Oblivion. It goes a long way toward making the game a little less like a Road Runner cartoon.
Don't forget the
Unofficial Skyrim Patch.
I usually don't bother too much with followers but
Ultimate Follower Mod should make them a lot more useful and interesting. I have it installed, but I really haven't put it to the test, yet.
Weapons of the Third Era keeps the weapons interesting.
