Posing looks fairly decent in both.
For 1, I wish the groom wasn't as square to the camera so the bride's dress wasn't covering his feet. Also, you could have avoided overlap with the couple just to the right of the B+G--but this doesn't bother me too much.
I'd say the main areas of critique for the images are:
i) backgrounds--if getting cleaner backgrounds (ie. no people) wasn't possible, perhaps this wasn't the ideal location. I shoot in some of the busiest areas of the downtown of a large city on the weekend and I'm always able to carve a spot where it seems like my bridal party 'owns' the town.
ii) as you suggested, the way these are lit could use some work. Your options were to either blow out the background and just concern yourself with exposing the subjects (it looks like that's what you did in (2)--and it works fairly well), to use the direct sun as your main light (put 45 degrees behind your shoulder); or you could have kept the sun behind them and popped in some flash.
The sun looks fairly low in these images--was it still squint inducing ? if not, I'd have used the sun in the first. For the second photo, because it's fairly easy to light 2 people with an off-cam flash, I'd have brought the exposure down 1.5 stops and lit them with a speedlight + umbrella combo.
