Great start!!
What tool did you use up to this point?
I see several areas that need addressing, but I will start here.
Let's look at her forehead. See this crack?
Here's your repair. You can still see a line of demarcation. There's a tonal difference that needs to be blended.
Done quickly for the demo, here's more what a blended tone might look like. See the difference?
I primarily used the Spot Healing Brush Tool to clean up the scratches. I then used the Brush Tool with a Skin/Spatter brush to blend the tones.
Will cover some more areas later. Would like to see how you make changes on her forehead.
