I wanted to give this a try myself but couldn't find any instructions, therefore decided to wing it.
I opted for Copic markers as my colouring medium and as I do not own any real brown I chose warm tan and orange hues.
I started by stamping the images using Tuxedo Black. I coloured everything using alcohol markers and then added subtle highlights with a white gel pen.
