The Player Statue is a block you can place down which looks like a little player, if it has no player name attached it'll take the skin of the user that placed them. You can rename the Player Statue in an anvil to attach a username (Shift clicking does not work).
If you right-click your Player Statue with Phantom membrane it'll become a bigger variant which behaves like an armor stand with the ability to pose them, perfect to make your Minecraft worlds feel more alive.
This mod is a standalone version of the Player Statue feature from Statues.
