I hope Mark posts about this a little too - because he's really the holdout, although I'm also holding out.
I don't really believe in first glances. Not because they're bad luck, but because they are poorly executed. Every time I see them, the bride walks up behind the groom and she taps him on the shoulder. Then he turns around and they get gooey.
The whole point of that giant aisle, besides being surrounded by people who love you and them all watching you walk to your beloved, is that anticipation where you get to stare at each other. No bride would walk down the aisle, tap the groom on the shoulder, and then have him turn around. At least not that I've ever seen.
I'm not ruling a first glance out, because the idea of getting the portraits out of the way and actually eating food at cocktail hour, I think, sounds darn tasty. But I want to come up with a better execution - something that captures that anticipation, and something that lets somebody get a picture of the look on Mark's face when he's really looking at me for the first time in my dress - and that should be a long enough time period for him to cry, not just a five second "oh, hello, girl that tapped me on the shoulder."
