I like them. They have good composition as far as I'm concerned. The only complaint I have is the white balance. I think its a bit off, cause your wife (lucky guy) looks a little cold. Usually this means the photo has a very slight blueish tint, but I could be wrong (I have been before, and I will be again). Also, if you want to you could always smooth out her face on photoshop. She has a wonderful complexion, but I've found that a little bit of smoothing usually doesn't hurt. But its totally optional, too, and its a great shot with or without it. Also, with #1, the rule /tip says you should have your subject face the center of the photo, but I don't think its a problem with this shot. I'm not feeling like she's uninterested or anything (which I do with some photos of people pointed off-photo)
If you wanna get really technical, I might crop out how her hand just BARELY comes back in to the photo in the second one. It looks like you did a good job of this overall, but a really watchful eye might get distracted (someone with photo ADD, lol).
