Gary --Cal,A good start, and I'm sure you are going to have a lot of fun
developing this skill! It's getting late, so this will be brief,
but some thoughts that came to mind (from a purely technical point
of view):
-Need to watch the shadows, especially those on her forehead.
Sometimes it is useful to look at the shot upside down, or squint
your eyes so that you disassociate the face from the "bright"
regions and any "subject mergers". Besides choosing a different
location / direction / time of day / weather, look into a reflector
(such as a 5-in-1) that can work as a white scrim. Outside, you
will get beautiful soft light through the scrim without the hard,
short shadow transfer. Also, with the lighting, note that if all
areas are in focus, the eye will often be drawn the the brighter
region, which might be her arms in this case (which are brighter
than her face).
-Your model's comfort: if it is bright, shield them from the sun as
otherwise they'll be squinting and you will get a harder
expression. Plus, you might lose the "twinkle" in their eyes, which
gives life to your models. A scrim/reflector will solve this.
-Watch for subject mergers and points where joints are "cut off".
Hands are a good example of something that one should be careful
about (as they can sometimes draw too much attention). Sometimes
rotating them away from the plane of the camera, or (in the case of
your photo) moving them to a different position (eg. move the guys
hand) may help to diminish them.
-Your lens might be a bit short for typical, flattering
portraiture. A good starting point would be an effect length of
85-135. Otherwise, you have to be careful about positioning of arms
(or other parts) closer than the face, as you can get some
unflattering exaggeration/distortion.
I know you're going to enjoy this, so keep at it & good luck!

You raise lots of good points and it gives me something to think
about before I try this again. I am going to look at reflectors
and see just what is involved . On the rare occasion that I do this
though, I imagine it will be just me and person(s) that I am doing
this for. I am trying to figure out a better way of using the
flash. Maybe a wooded area next time. I think the biggest problem
was the time of day and the harshness of the natural light. Thanks
again and happy holidays.

Without an "assistant" (spouse, friend, etc.), it can be difficult using a reflector properly. I have had some luck using some Manfrotto light stands with a boom to hold the reflector. However, this does not work if you have any amount of wind
No matter what, having the reflector (like a 5-in-1) can offer so much to your outdoor, natural-light portraiture. It is also very cheap and compact (they fold up into a disc).
Good luck,
Cal.
A quick example of how a reflector can help my in-the-sun shooting:
