I did some very basic tone curve and color toning adjustments as well as a spot white balance modified to a more yellow/green hue. Here is the pp3
I then took it into GIMP 2.9 for subtle skin retouching and more color adjustments. One being a Fuji 800Z film emulation on high in G'MIC masked off her face. There were probably quite a few hue/saturation adjustments and some dodging and burning in there somewhere.
I applied two textures, one with a black and white graininess and vignette, the other with a golden hue. I set the B&W grain to soft light and the golden texture to overlay (so glad that's fixed) and applied luminosity masks with some hand brushing here and there to keep them off her face. I believe I got them both on DeviantArt, but it was years ago, so I don't remember who to attribute them to. I can probably come up with something similar if anyone is interested.
A wavelet sharpen and a Kodak TMAX 400 G'MIC grain layer later and I think I was done.
