Judging by eye, it looks like you are getting pretty much what one would 
expect.

Reading the esri post, reminded me that there is a web page describing 
how to get the generalized hillshade that is described in the same post 
before MDOW:
http://www.pdcarto.com/mtncarto02/GRASS.htm

Maybe of help to someone.

Kind regards,
