I do like the light in this one, a great deal.
So, here's my take.
Some spot healing burning and dodging on the original to clean up the skin a bit. Add a layer with a light gaussian blur and a layer mask, paint in "blurred" layer on her face, to varying degrees, to taste. Photoshop has a slicker way to do this, I think, with their fancy brush tech. GIMP I just use layer masks for everything.
The add a glow effect, which is another layer filled with, in this case, solid FDBFCF which is more or less her hair color lightened up a bunch. This layer also uses a layer mask, which is a greyscale copy of the original again blurred to taste. This has the effect of layering "light reddish fuzz" over the image in proportion to how bright it is. The dark areas get left alone, the brighter areas glow outwards subtly. This also has a smoothing effect. This layer is translucent. This is the opposite of "enlarger diffusion"
Since this effect has a brightening effect overall, insert a translucent black layer between to push the values back down.
Since things have gotten a bit desaturated along the way, adjust saturation and curves on the base image. Adjust transparency of everything to taste:
Also painted the problematic shoulder, somewhat clumsily I see.
