Some zombie villager textures are inconsistent with their living counterparts. The notable ones I found were:

Weaponsmith: Missing gloves, black lines near the middle of the arms (caused by copy-pasting the villager texture; the villager's gloves end at the zombie villager's arms), brown parts on the eye patch.

Armorer: Missing gloves, brown part under the mask is arguable whether it's inconsistent.

Nitwit: Sleeves cut off at a straight line, with no tattering.

Mason: Missing gloves.

Leatherworker (Not in picture): Missing gloves.
