Hello Treeka, If you do not have much experience at modding, the first thing to do is get a good mod organizer, I would recommend Mod Organizer 2. You will also want to at least get LOOT, (Load Order Optimization Tool). For learning how to install regular mods and useful tools I highly recommend the tutorial videos by Gamer Poets available on YouTube. I found his videos thorough and they are easy to follow and cover many basic installations such as SKSE, (Skyrim Script Extender), SkyUI, (Skyrim User Interface), and how to set up and use MO2 to install mods. As to the categories you listed my advice is as follows; 1)Objects Static Mesh Improvement Mod, (SMIM) by Brumbek For the sake of, "ease of use", I would try out the Cathedral Concept Mods because they are very compatible and produce excellent results. They cover: Lighting - Luminosity Mountains - Majestic Mountains Weather and Seasons Water And many more. For NPC's try Total Character Makeover Once you are comfortable with these, (together they will vastly improve the look of the game), you can look for others you may want. Hope this helped get your Skyrim lookin good.
