Hey Bryant, thanks for posting. I think these could be much stronger with a bit of tweaking on the posing. For example:
1. I would bring her shoulder that is facing away from the camera (her left shoulder) a bit more towards you. I think a 45 degree angle works best, and this is just a bit to far out. Also, try to move the bouquet a bit more away from the body. I have learned, if you can bend a joint, bend it. Having straight arms really makes the image static. If you drag the veil a bit over her right shoulder (the one closest to the camera) you will also be able to make it more appealing. No matter the size of the person (man or woman) showing huge flats of skin makes them look bigger.
2. Same with the posing I listed above, but here the biggest culprit is lighting. It could have used some fill flash, or (my favorite recently) a reflector to either bring in light or to diffuse it coming down.
3. Straight on to the camera and not appealing. In a situation like this, I like to try to keep it very symmetrical, and bringing the veil over her right shoulder would bring a bit more into the photo.
4. Here I think this is your strongest one, and you are almost there with the posing. I have found that when you are doing a pose like this, you have to really accentuate the pose. Tell her to put her weight on her back foot pointing out to the outside of the sidewalk and her front foot pointing towards you. Then tell her to REALLY pop her hip out. It is very easy for this pose to be muted with a big white dress (as most wedding dresses are) and although it may seem extreme, it shows better in the photos.
You got the WB and exposure right, so it is obvious you have the basics down. All you need to do is get a bit stronger in posing, and that comes with a lot of practice. Keep it up!
