As my biggest mob statue project so far, I built 144 Llama Mob Statues at a 1 pixel : 2 block scale.

There are four different base color types: brown, creamy, white, and gray. In addition to that, there are 17 carpet decorations (16 colors + wandering trader style) and a set of chests that can be added to the llamas. In total, that gives 144 different statues.

(The white and gray llama statue ended up looking very similar, but the mobs also look close to one another in-game. Combined with the limitations of the block palette, I ended up with two statues with only small differences. I thought about making a distinct, darker gray llama but ultimately chose to keep the colors somewhat true to the game.)

The download includes Litematica and WorldEdit schematics for all 144 statues as well as a world with all of the statues.
Feel free to download and use the statues however you like, but please give credit if you do :)
