Googling also gave me this link, if you're interested in other photographic 
references: http://www.randafricanart.com/Henfrey_Boli.html.
I can see both types of surfaces here.  Judging from these (at the bottom of 
the page, esp.), your attempt at the texture of the surface seems really 
good.  Is that one from the MMOA the same one that you were looking at (near 
the bottom of the page)?

The texture of your original also makes me think of brownies.  It seems to 
be a great multi-purpose surface texture: paint coming off walls, desert 
mud, etc.  I may have to play around with the code you supplied.  :-)
