Looking for skybox textures

Hi guys, so I was looking for some skybox textures, but no luck finding the right ones, what I'm looking for is a sky with clouds - even though I don't know anymore how to make that, I had an example WAD if anyone has it, it was with a night city I think, anyways, what I'm looking for:

Daylight sky, 3-ways: one side should be a city in a distance, best if on hills, other 2 sides should be mountains connected to the "city" and third one should be blank sky (sea side) if anyone could help me somehow I would be really grateful (will post WIP wad if I make "playable" advancement)

There are a lot of sky textures around here. Try this website but im not sure.

already tried before but all links are dead, that's why I'm trying my luck here

You're in luck, Wolfman posted a fresh set of links for those skyboxes about halfway down this page.

thanks grey, hopefully I'll find something suitable

Wait, why are they dead? Are you joking me? I already checked it out, and its working! Oh, nevermind.....

That ghost just stealt my help again...
