Currently, both stand tall with straight backs.
Both polymorphs would look
more fitting [imo] with their respective ESO foes, if both had a fitting hunchback visual, as both of those feature, as foes, in ESO. [Troll polymorph almost looks like a target dummy, is so straight backed and lacks idle animations that would befit a troll or troll polymorph.]
Also, what do others think? Favor straight back or hunchback, for these two polymorphs?
Some images showing how they look as foes inside ESO:
