Hi Kara,
I didn't even notice that #1 was an over-the-shoulder shot until Ernst pointed it out. When framing these kinds of shots, I usually try to include more of the parent so you can really see the relationship. Here's what I mean:
You also had questions about the lighting on #2, which I think the images above may help with too. I asked the mom to stand just inside the opening of a French door in her kitchen. So there was no light coming from over their heads, the only light was coming from the open sky outside the French door. If you look closely at your photo, you'll probably see the shadows under the eyes and also under the eyebrows (particularly close to the inner corners of the eyes). In the photos above, since the light was directional and was only coming from in front of the baby, there were no shadows under the eyes and since she was looking at the sky, there are nice bright catchlights in the eyes. Also, since the light on the baby's face was several stops brighter than the light inside the house, the background went pretty dark (which I like, in this case).
When you are shooting outside, try to find places that create directional light - meaning the light comes in from only one direction (or two directions), not from all around. Porches, overhangs, etc. are great for this. That will help prevent the "raccoon eye" effect. To see the effects of this, ask your husband (or anyone else who can follow directions, haha) to stand outside in bright sunlight. Look carefully at how the light falls on his face and how the forehead and facial bones at the eyebrows most likely create shadows around and under the eye area. Now take a large piece of stiff cardboard and ask him to hold it over his head (or move him to a porch or other shaded area with his face to the sky) and watch how the lighting pattern changes. The shadows should go away. To create GOOD shadows on a porch, instead of shooting straight toward the subject while they are facing directly toward the sky (as I did above), you can position yourself so that the open sky is to your left or right (not to your back) and ask your subject to turn their face to look at you. You want to look for light in both eyes and a patch of light on the cheek that faces away from the sky, like this (in this case, the subject's right cheek):
In this photo, we were standing under a porch, the open sky was to camera right and the wall of the house was camera left, blocking the light and creating the shadows on the right side of her face (camera left).
Didn't mean to hijak your thread with posting a bunch of other images (and I'm sure these are not technically perfect examples), but I thought it might help to give a visual aid to what I'm trying to explain. :) A book on this subject that I've found really helpful is
Available LIght: Photographic Techniques for Using Existing Light Sources by Don Marr.
Hope this is helpful...
