There are three main problems:
1. The images are underexposed. Watch the histogram on the screen when you take the photos. If you took the photo in RAW, Photoshop can fix this, but it will create some grain.
2. The light source is directly overhead, creating shadows on the faces. It needs to be a little more to the front of the face, especially with the woman, because both eyes are in shadow in both of her photos.
3. The white balance is slightly off in the first two photos.
Using natural light can be a challenge in getting good photos, but the rewards are great. I second the suggestion to learn Strobist Lighting 101. It will teach you what good light is. With good light, you can completely eliminate the need to use Photoshop.
