I decided to go with B&W because I am not good with colours. Did minimal processing as comfortable. Removed some of the blemishes but not all of them for effect.
1. gmic → crop (1.5:1) → inpaint cracks → local contrast (guided) → norm → smoothstep (curve)
2. GIMP → heal (dark spots on face)
3. gmic → sharpen (LoG) → resize
