If you shoot her against a bright background as you have here, then the danger is the over-exposure you see on the right hand side. Adding to the exposure works best when the light is even throughout the frame, otherwise you end up with other problems.
I would shoot on a bright, cloudy day or totally in the shade. That would even the lighting and exposure but the colour temperature would need to be warmed up a bit to negate the slightly blue shade. Using a reflector would also diffuse the light, as would a flash with a diffuser on it, to mention other possibilities.
Afterward, many model photographers use a portrait plug-in to Photoshop or software filter plug-ins to get the skin colour as close to their memory of it, as possible.
By the way, you can easily see problems in your shots, if your exposure "seems" satisfactory, but the skin colour is slightly different in every shot.
