This pack basically retextures The End and related items, turning it into The Sky Dimension. It gives you a different experience of Minecraft's concept of "the end", a dimension with divine and somewhat heavenly vibes in contrast to the eerie and mysterious nature of the original End Dimension. Sky dimension lets you feel eternity rather than uncertainty in exploring it.
To specify, here is the list of changes in the game
Note that I'm not an artist of any related kind nor a coder, so I wouldn't assure this as quality content. Rather, I want to bring my imagination to life, and I want to share this to you, especially pack creators, to give new ideas. If you do so, let me see. And by the way, these textures turned out to be so since I really put some lore behind each. Thank you
