Archer should hold the bow with his/her left hand
Your character in Morrowind is right-hander so he/she should hold the bow with his/her left hand.
Maybe Morrowind creators never shot a bow, but it would be nice to have some option in OpenMW to correct this nonsense.

The bow use and animations are horrible in both Morrowind and Oblivion (don't know about Skyrim), but I think it is beyond the scope of the project to fix it, since it would involve redoing original artwork instead of just a different implementation on the engine.
However for post-1.0 it would be interesting to make it possible to do the necessary work in a mod. Then someone could create a mod that provides bows held in the left hand.
