What are some good mods for skyrim to make it look better?
Check RealVision ENB.
Randy Savage Dragon Mod and Dr. Zoidberg crab mod.
climates of tamriel, realistic lighting overhaul, realvision ENB, 2k textures, and all of these are found on the skyrim nexus.
I second Climates of Tamriel and Realistic Lighting Overhaul. The two of these alone give a huge boost to visual and even audio immersion. I can't recommend any particular ENB, but there are a lot of flavors out there.
