Very beautiful shots. And you were lucky to have such a beautiful model.
I agree that a boost in contrast would help some of the shots, but you don't need a lot. And maybe a slight color shift. In the first one, maybe +5 red and -5 yellow. With several of them, her being in the shade and the background being in sunlight makes her light seem a bit dull. As mentioned, some fill light would help that.
In the second shot, that bright arch steals my attention. I think if you block it out with your hand, you might see what I mean. Now the bride and bouquet have the light and the attention.
I really love how the light falls on her in 8. The bright light in the background is a little distracting. I would try to compose a little different next time so that you don't have those bright spots.
One of the tricks I was taught along with "check the corners" and other things was to check for "bright". The eye tends to go to the bightest parts of the image. Are the bright spots important? Are the parts that are lit where you want the viewer's eyes to go? It's like looking for telephone poles. In the first one, the sunlight on the side of the tree trunks and flowers (and even her shoulder) is a bit like having a power line in the image. It's not as unnatural, but it can be distracting.
