Left-handed bows are common enough that I sometimes have to look twice to see if a solo archer is shooting right- or left-handed - ditto when looking idly at a solitary bow. If you get several archers together, of course, it's usually fairly obvious which one(s) is/are left-handed ... Unless they all are, of course! (In which case you get an interesting double-take effect of the "what's wrong with this picture?" type!)
