Skybox Winter Day

"Kindness is like snow, it beautifies everything it covers."
By Kahlil Gibran.

First Picture shows your skybox in 360.
Second shows the front view.

General advice for skyboxes:
Adjust your (directional)light(s) in your scene to the (if there is any) light source in the skybox (like a sun, moon, star cluster etc.). Play with you light strength, range and Sky brightness (you find this in the Scene settings) to fit the skybox to you needs and give it a nice and realistic look.

All skyboxes are at least 2048x12288.
