I always enjoyed the look of Rollie shots with fill flash, and yours are no exception.
For many years that was my go to for weddings and the like, though I had Rolleiflexes and the big Braun F80 flash pack and head, with the very fast for the time, 2 second recycle, It was a real power beast and you could shoot larger groups outside, with flash alone at F8 at 400 ASA.
