I'm redoing some of my old Steve mobs since now I know how to texture,
compared to what I can do now the old ones look like garbage: https://www.planetminecraft.com/mob-skin/rabbisteve-next-generation/
So these are what I am remastering:
-Rabbit (all colors); Phantom; Iron golem; Snow golem; Fox (+ Arctic); sea turtle; bee (+angry & nectar variants); guardian (+elder); polar bear
So yeah uh expect a lot more changes (blocks, items & "entities") for the next update of the NarcissismCraft texture pack.
