I have plenty of experience modding games and SKYRIM is no exception..
Using the ENB mod you can make Skyrim look so good it’s unbelievable.
A List of the important Mods Used in this screenshot
SKYRIM HD via NEXUSMODS
REALVISIONS via NEXUSMODS
ELFX via NEXUSMODS
ENB via ENBDEV.COM
COT via NEXUSMODS
Surpreme Storms via NEXUSMODS
Enb/realvisions enables Depth of field blur and other features that make the game look so damn good..
Sadly ENB has quiet a high tax on performance especially in 4K (2160p) so I have a very good performance tweaking guide for ENB I will post it soon.
