Closeup of Tree and Hillside (Oil Bar Painting as of February 21, 2015)

I have been working on a oil-bar landscape of a late October scene that I photographed at Appleton Farms (in Ipswich, MA). I took this closeup yesterday and it shows what I was working on, which was negative space: adding light blue strokes among the branches and leaves to allow the sky to be seen through the leaves .
