You have some nice images here, Valerie. My favorite is probably the veil shot followed closely by the shoes shot.
Some of these could be improved quite a bit with some additional post-processing. The first shot by the tree, for example, could be improved IMO with a subtle dark vignette around the edge of the frame and a lightening of her face.
The combination of her hair hiding part of her forehead, your shooting from a somewhat low position, a focal-length just barely long enough to be optimum for a portrait, and sometimes very diffuse lighting has widened the bottom part of her face in some of these. You can see this particularly in the "lady in red" shot and it becomes a little more noticeable when it is compared to a shot like "in the alley" where the longer subject-to-camera distance and the increased facial sculpting of the light has helped avoid the "jowly" appearance. You could do some dodging and burning to the face in the "lady in red" image and correct some of the effect if you wanted to invest the time.
The alley image is very, very nice where the lighting is concerned. What brings it down a little for me is an expression that is starting to look a little bored/tense and the bouquet stems in the hand. A tiny bit more of twist in her pose might have been nice.
The shoes image is very cute. I would just again suggest a subtle dark vignette and a brightening of her face.
The frame shot just doesn't work for me. Besides the pixelation (possibly from re-sizing), the blown areas of her hair and hand and the way the light hits her nose are the negatives that detract from what is probably one of those "but I really, really want this image to work" images.
The pearls image is nice but the busy, almost-in-focus background combined with the offset face gives it more of a cellphone/snap-shotty quality than it probably deserves. I would try a subtle, dark vignette again and boost the contrast in her face a little. I would probably warm up the white balance a little, too.
