I thought that the green sofa is distracting and so is the bright background. Therefore, I used the great LAB tab in RawTherapee to reduce the colour of the sofa and make the white curtain a bit less bright. Then used the L curve to accentuate the face and darken the dress. That is all. So just used one LAB tab. Oh, yes I also straightened the sofa and added a soft vignette and a bit of haze removal.
Hope you like this.

Very nice portrait @FWinegrower
, you have really caught her alertness and sparkle in the eye!
PS: I did not crop the photo as her face being a small percentage of the photo with large featureless background seem to accentuate her frailness and hence the fighting spirit of positively facing old age.
