The problem is that your sky is Hemispherical, and is only the top half of a full environment. There are some things to do. You can add more pixels to the bottom (make it twice as tall, these bottom pixels will become the ground); for simplicity just make it pure black. Another thing you can do is change the texture's scale to 0.5 in its short direction (this will scrunch it up to where it needs to be). The texture will be repeated below it or above it, so you might want to change your border mode to Clamp Value or Black.

Thank you.!

and as far as projection would you keep it spherical or make it cylindrical?

Definitely spherical. But if you're using the regular Texture Environment then it should be pre-mapped already
