Hi David, though not a bad shot, theres a few areas where it could be better.
The use of f/1.4 was not a good idea, as it is so shallow it has left her nose out of focus entirely, and parts of her eyebrows. Using at least f/5.6 would be the way to go. You would then have the option to soften evenly post processing
You appears to have been very close to her when the shot was taken, and the result is distortion of the parts of her face closest to the lens, and you may have made he nose appear larger than it actually is (apologies if I am not right here)
The light is flat, - which may be what you wanted, but portrait can often look better with a little more light from one side than the other.
The composition places her eyes too low in the frame, - eyes need to be on a third, so staying back a little further would have given room for cropping to place the eyes while retaining all her head.
Ive loaded 2 mods, second one is a little softer than the first. Ive re cropped; sharpened where I could; applied differential lighting and corrected distortion.
Hope you find this helpful,
