Another test.  This one was done in watercolor as opposed to inkwash for the last two.  For the inked lines this time around I mixed a combination of brown and black inks to get the right level of dark brown I wanted.  The watercolors give the benefit of being more forgiving than inkwash, which tends to dry faster and is more permanent.  The watercolor allows me a longer period of wait time if I decide I want to blend it some more after letting it dry.  I like the look of the inkwash better, though.  The search for the right method continues!
