3. The top and bottom sides of the left/right arm parts (for the folded arm model) are inverted, and should be swapped.

Vexes:

(The issues with the vex's texture were fixed in 22w45a, when a new model was made)
The vex additionally has the bottom of the head and the top of the tail not matching the bottom pixels on the head's sides and the top pixels on the tail's sides respectively.
Additionally, when a vex is charging, all of it's affected body parts (including the bottom of body) do not get the red pixels. This is especially noticeable on the bottom of the head where there's an abrupt ending of the red pixels.
