I too liked the images. I did not see many guest and "spontaneous" images, but I suppose they were on the rest of the roll (I think only 13 were shown).
I'm curious about a few other things:
By comparison, how many digital images did you shoot?
If you weren't self limited to one roll of film, how many would you have shot?
Have you shown the b&g the 36 film images and gotten their impression of the wedding coverage (on film)?
