Alright, well, I'm not quite sure what is up with the black bars in seemingly random places... but anyway...
#1 I like the pose, traditional etc. but it looks a little cool color temp wise, and it bothers me a little bit how blurry the ring is. I think more DOF would be better, mainly because of how prominent the ring is in the shot.
#2-3 Still probably a bit cool, not bad though. I like #3 better
#4 I know this shoot was "natural" light only, but I think this could have been greatly helped by a reflector or some fill or something.
#5 this is a cute shot. not sure what I think about the leaf in front of their faces, but still nice
#6-8 of these 7 is my favorite, I like the emotion in that one. Other than that, the sun is really quite harsh in that shot, and difficult to work with, some shade or fill flash could have been nice to knock out the slight racoon eyes you have.
#9 This is a nice enough shot, I think I may like it better in color because I feel as though I have to search to hard to find them. Also, just a suggestion, but I think it may be helpful to include a small bar between the two images I think it looks disjointed with the trees hitting in as they are.
#10 this one is ok, again, not sure about the purpose of the odd format and the decision to go with a huge black bar as it's not really printable. My main thought is that he looks rather red, which is different than the rest of the photos.
#11 doesn't really grab me, but I'm not sure why not. I know that in the first images she looks really pale and here she looks dark, but other than that, it seems to be fine. It has an awful lot of the background and little of them, but I'm not sure that's a problem.
#12 good basic engagement shot, but her coloring looks really odd to me. Looks to be rather yellow, when again it doesn't seem to fit with what she is in earlier photos.
#13 I love this shot. I'm not sure how much they will love it as you can't see them or their faces, but I like it a lot FTW
#14 nice cute shot. it's a close second to #13
