I know what you mean =P you shoulda seen my first skybox ever, it was horrid. But in the two island ones, I was trying to create a happy median on altitude. Too high, and the edge of the world becomes visible. too low and things start to look a little strange. I might redo these, lowering the altitude of the camera about 25-50 meters. Thanks for the review though! =)

That is one of the things I was actually thinking about updating. Maybe adding snow in the mountains, and trees/greenery in the islands. Yesterday I figured out how to work the advanced tab in the layers that allows you to control where and how the layers affect the land, instead of them randomly throwing it all over the place with no rhyme or reason. It turns out that I had the slope buttons mixed up. I'll soon be updating these.
