If you are looking for an unusual and really high-quality texture pack that will differ from others in special detail then download Pixel Legacy for Minecraft. This pack was originally developed for the Java version of the game, but the author made a lot of effort to transfer it to Bedrock. Now all players of the portable version of the game will be able to try this pack and enjoy the views of the new world.
This mod will change a huge number of blocks, textures and tool models. The changes will affect both the upper and lower worlds, which will look very beautiful and unusual.
