Texture [Request] Stormy Darker Skybox

[RavenStryker]

Okay, so I was wondering if someone could make me a nice dark stormy tf2 skybox for my map. I am using sawmills right now, but I don't like how one side it more lit up and has sun coming through. I'm more going for something that looks like this all the way around:

If anyone knows how to do this and could do it for me it would be much appreciated.
Also if you think it should be altered a little bit to fit the map there are some screens of what it looks like above.

sky_night_03 of the Swamp pack was meant to be used for stuff like this, so... that may be something to take into consideration.

o0o0o, i didn't know that there was custom skybox textures in there as well. I figured it was all models and normal textures.
