MCMojang resource pack is a texture pack with the same style as the official Minecraft website. Bright colors and stylized textures make this texture pack look fresh and bright. I think most players will like this style of texture pack.
In terms of specific details, the MCMojang resource pack's textures don't have too many details, because as you can see from the Minecraft artwork, textures are mainly defined by bright colors rather than just relying on details. Vibrant colors, paired with clean and stylish textures, make the game world a joyful anime. This pack will also change the in-game sky to ensure it looks just like it is depicted in the Minecraft artwork.
It is important to remember that using Optimine is highly recommended as it allows the sky map and fog to work as is. MCMojang resource pack has x16 resolution because it doesn't need high resolution to reflect its art style.
