No offense, but I still prefer flash (if it's allowed). There's still a lot of blur in those photos.
And some in yours too...
For flash.... especially in a place like i chuch.... irritation/distraction factor.
I would take natural light over flattening flash (if you cann't bounce...still annoying but less than in the eyes)... and be lucky anyday.
Even if not actually because of SR/IS but subject movement slightly blurred.
And shown to subject (not a PERFECT model) probably just as happy NOT razor sharp)
