Sure!!
So as I mentioned before I used Substance Painter for this approach so I started with a base color
that is reddish grey with roughness about 0.6

Then I applied baked light filter

I adjusted the material, sky color, sun, and horizon

and the light1 directions, while left the light2 without any changes
Then I created three moss layers with different shades of green
the first one is the dark one with roughness 1 and applied metal edge wear
The grunge is cloud 3
added some blur slope and painted some parts of the statue
The second layer is lighter with the same roughness and metal edge wear and blur slope but also applied some light generator to direct the position of the moss

The third layer of moss is a yellowish one
with the same generators but without the light gen.
I painted some in different parts of the statue.
Next I added some reddish shades that are in many statues, I don’t know their labels so I called them rust LOL 
I gave it a light reddish color

same settings and painter on her face, and chest
then I added an intense one in some parts of her face and body
Next the cracks
I picked a dark maroon color, added a fill layer, and to it I added a cracks alpha that I downloaded

I changed the blending mode to
soft light blending mode, and masked some areas that I didn’t want the cracks to be on the figure.
The last layer I gave it a goldish color with a slight metalness which was a Happy Accident 

with a fill layer to give it a slight goldish color with
soft light blending mode

and voila!
Here are all the layers
I hope I didn’t miss anything! and of course would like to answer anything
