Ok a witch has made a wax voodoo doll of me that still has a few uses left. Since that time I turned into a werewolf. While under the effect of the transformation will the witch still be able to control me with the wax doll. Keeping in mind it now looks nothing like me.
RAW it'll still control you. There's nothing in the ability that says if the target changes forms the ability wouldn't continue to control you; you can think of the image as a representation of you to the witch. Similarly, a friend was alter-selfed into a copy of you, the wax image wouldn't now also work on them.
