Need help/tip on creating vecchio organic material

[Kost4d]

Hello!
I am ashamed, please help!
I cant create some vecchio organic material - it is just bronze with patina, but I am just stucked!
here is the link for reference https://www.google.com/search?q=vecchio+organic&rlz=1C1SQJL_ukUA787UA787&tbm=isch&tbas=0&source=lnt&sa=X&ved=0ahUKEwiMs6e22v7gAhXxh4sKHVoiAwcQpwUIHw&biw=1745&bih=852&dpr=1.1#imgrc=jvg85o4Fr6eSvM:

As a base I used two native copper Corona material from the library with different glossyness then mixed these two using layered mtl and a fractal noise mask.
The result is not realistic... who can help?
Maybe it better to use just a hi-res bronze texture?

Something like this?

It is corona layered material which handles the dull sheen reflection along with a base material that is made up of a bunch of different mixed grunge maps.
