I hope this is a good place to post this topic; I thought about several including the Beginner's forum but I am definitely not qualify as a beginner and when I post there I tend to get answers that miss the real point of the question and assume I don't know how aperture works or something 
I have read and watched dozens of things about using open shade, and frankly they all say almost exactly the same thing, I assume because the concept doesn't seem to be all that complicated for there to be multiple takes or nuances for difference pieces to get into.
Yet there has to be something more to it than everything gets into because I just can't seem to employ the idea successfully.
Some background: one problem I have when shooting in natural light is getting skin tones which are lacking in good, natural color and look not really ghostlike but definitely what one might call a bit washed. Here's a photo of mine which has decent tones in the face and looks the way this person actually looks when you see her in life:

Here's another with a slightly different quality of light, to get the idea:

On the other hand, here's a one with the sort of tones I get more than half the time when shooting in natural light:

Now this is from a relatively dreary winter day and so the more washed look makes some sense here, but honestly this was after a lot of work to fix the tones and I still think it has a certain quality to it that amounts to a a lot of bland white with splotches of red and frankly I went ahead and stylized the rest of the photo to try to make the overall thing make sense with the way her face looked and it would stand out a lot more otherwise.
Here's another that really shows what I get a lot of the time - first the original, and then after working on it:


The original is very flat and colorless in the face. The edit is better, but it exemplifies what happens with almost every one of these photos: even if I spend hours on a single image the best I can do is something which is more colorful but overly orange or otherwise saturated with slightly off colors. I think the problem is that there just isn't enough natural color in the original to bring up and so I am essentially trying to add colors back that aren't there in the first place.
After personal reflection and asking advice of more experienced photographers one of the main diagnoses I have for this skin tone problem is that I am frequently shooting either on sunny days with subjects deep in the shade and so not they aren't getting a good quality of light on them to bring out their color - essentially, the colors are being "naturally underexposed," OR they are being shot in flatter, overcast light which has the twin effect of overemphasizing the highlights in a person's skin and making things look too flat, also resulting in bland and washed out colors.
That's a longer preface than I intended, but this brings me to open shade. I realize that open shade is not the only thing to do to deal with this issue (feel free to suggest others), but it's certainly one way to try to get better lighting on people in both of these general cases. The problem is that I cannot get open shade to "act" like anything other than regular deep shade.
Everything I have seen talks about open shade this way: find a place where there is a sharp cutoff between the lit and unlit area. On a sunny day, you can just find the line on the ground where you have sunlight on one side and shade on the other. Put the person just in the shade and face them out in the direction where the light is coming from. The light should generally be a large open area of light.
That's it. That's all everything says to do, and it is presented as a very straightforward, very easy thing to do. My results? always just like the example: overly shaded, no colors to speak of in the skin. Here is an photo I took for no reason other than to demonstrate what I am talking about:

Look at the legs of the toy and the bottom of the skirt and you can literally see the line of sunlight - that's how close she is to the edge. I had her stand so her face was in the sunlight and then take one step back. In front of her is literally nothing but sunlight, along with a big open sky.
Behind her is the shade. I have had one (very skilled) photographer look at the sunny area in the distance and tell that the problem here is that behind her is brighter than what she is looking into, but that doesn't make sense to me because what she is looking into is entirely sunny and warm and bright while behind her is hundreds of feet of shade. If I turned her around and we walked all the way down to that other line of sunlight and had her face that way, then she'd have the bright, bright sunlight she is currently looking into that same distance behind her and the situation would be the same.
I was also trying to expose for her face here, not meter for the background light. The issue isn't per se the luminance - I can easily bring the luminance of her face up with this RAW file and get what looks well exposed, and I took some shots with greater exposure so she was naturally brighter - but it's that the quality of light leaves her face without much depth of natural color that I see in so many "open shade" and other natural light photos.
Thanks for sticking with me this far. Please understand that the example I have posted here is just one example. I had already tried using open shade many times without success before I set out to take this one just so I had an example to demonstrate. In any case, I'd appreciate thoughts and advice.
