1 - I like the sense of emotion and action you got here. I agree, the background is pretty busy and I wish we were at a slightly different angle.
2 - Perhaps a snob but this kind of shot doesn't work as well with fake flowers IMO lol. They just look fake
The crop is a little off, I think there should be more on the bottom of the image, and I feel your B&W is a bit flat.
3 - okay, nice smile but at first glance this looks like you caught her in mid blink! Especially looking at the tiny bit of eyeball we see on the right eye (our right looking at the image). It looks really weird. Exposure is great though!
4 - I'd say this is my favorite one. The way it's composed eliminates some of the clutter in the background, we have a better view of the bride as well. It doesn't really grab me but it's sweet.
Overall focus and exposure look right. They only look soft to me in that 'this image has been resized and compressed for web viewing and has not had any web sharpening run on it to make up for that'.. way lol. they seem like they're probably in focus.
