Skins are one of the ways Minecraft players can express themselves! You can make whatever you want, there's really no limits; except one. The 8x8 (referring to the head size) skin format is difficult to work with, without looking like everybody else. The main variation lies within colors, hairstyles, and clothing choice. Imagine if there were unique faces, and a new amount of detail to work with! Of course it would still be possible to access the 8x8 skin format, but you can still go for a larger pixel size like 16x16, 20x20, etc, similar to the way the Alex model was added but the Steve model was still usable. This could incorporate a whole new amount of creativity! Realism can be easier and art styles would vary from skinner to skinner. As an artist I would love this. A new amount of detail could be unlocked like grooves and indents in shoes or the fine details of each piece of hair. I think this update would be fantastic for artists everywhere!
