When a witch dinks a potion, it shows up as if it was being held by a player, when it should be facing the witches' nose pointing up. This applies to all other 2D items as well by using the command:
/summon Witch ~ ~ ~ {CanPickUpLoot:true} – Then give them an item.
Also I like how the witches' potions finally have a color applied to them. Just my note.
