This wonderful Minecraft PE resource pack contains shaders for the sky. Created 3 different sky on different subjects: Super realism, Fantasy and Inside The black hole.
Unfortunately, texture pack extension is only supported on iOS and Android phones. Now you can easily build something that will resemble the structure of other civilizations. For example, a super realistic sky will make the game very pleasant, because the cubic world will have a real living sky.
