Ten sky cube maps perfect for renders or real-time apps. Maps are in .bmp format arranged into a cube map 6144 x 1024px. They are arranged in order: back, right, front, left, down, up. If you need a different order, each view is also included at 1024 x 1024 so you can arrange them in the order that your engine requires.

Below are some reduced resolution views included in the ten sky cubes.
Below is terrain surrounded by a sky cube rendered in real-time. The terrain is comprised of three textures, the terrain skin, and a detail map all blended together with a shader. The textures are grass, gravel, and dirt. The skin and detail map imitate cracked rock.
Below are high resolution sky cube captures followed by a couple random sky assets.
