What could I have done to improve this shot under these conditions? saying hello from Pittsburgh.
As you said, "lighting is everything" in portraiture.
Portrait lighting
Different subjects require different lighting techniques to bring out their best features . . . or to subdue their worst. There is a lighting method that is used more than any other because it is glamorizes most subjects. It is called "short" lighting and the result gives a "Rembrandt" style of lighting. It makes most people look more slim, (and who doesn't want to be slimmer?) and adds wonderful depth and modeling to the image. Here is an example of "Rembrandt" lighting. This is "short" lighting, meaning that the shaded side of the face is towards the camera.
Where you are does not matter, indoors or out. What matters is that in order to use any of the portrait lighting styles one must be able to control the direction from which the light is coming. In a studio this is quite simple as studio lighting is very moveable and controllable. Using existing natural light means that the light source cannot be moved . . . so the subject must be moved to accomplish the same thing. In studio the main light comes from only one source and direction. There is no ambient light being recorded to diminish the effect of the main light.
Out of doors there is light coming from all directions, sometimes harsh (direct sun) and sometimes very flat.(cloudy or foggy) Neither is desirable.
To control the quality and direction of light out of doors, several things must happen. We must get out of the direct sun from any direction, and we must go to where the non-direct sunlight is directional. Enter "subtractive" lighting!!!!
Subtractive lighting is just as it sounds . . . subtracting light from one or more directions. In the studio we have only one main light and we can add others from different directions as we wish . . . . out of doors we start with light coming from all around us, so we want to subtract the light from one or more directions leaving us with "one main light". For example we can move into the shade of a building and as long as the building does not reflect too much light, we have subtracted the light from the direction of the building. Add a roof as we would find on a porch or in a gazebo or under a tree and we have subtracted the light source from above. By repositioning the subject we can have the light fall on the face from the direction we want.
In elaborate on location shoots we also sometimes carry gobos to block the sun. Check out this site for subtractive lighting.

The above systems are using the existing light as our main light by controlling the subject position and subtractive lighting. Another method is to use the existing light as our "fill" light, and using an off-camera flash as our main light. It's like carrying your own sunlight and is very effective. Simply underexpose the existing light by about 1 F/stop and set the flash for proper exposure. Here is an example.
Hope that helps. Nothing is more fun that accomplishing a great portrait . . . keep on practicing and studying.
