Some nice photos there Jim.

Lovely portrait of the bride, very relaxed. I would lighten up her face since its facing away from the light source. Also just watch how you process these as banding is quite evident here.
IMAGE 2
Lovely portrait of the couple. I would have asked the groom to tilt his head the other way as it looks like the bride is leaning to heavily on his head and asked him to hold her hips with his free hand. I would also correct the white balance as its a bit cool making the dress look blue.
IMAGE 3:
Least of my fave. Only because of the processing done, it looks very antiquated. I'm sure this would have looked good without the white vignetting.
Good job overall considering its your first wedding. NO EASY FEAT
