Tree and Hillside (Oil Bar Painting as of February 10, 2015)

I spent a little time working on this painting this morning.  I am working from photos that I took in late October at Appleton Farms (Ipswich, MA). You can see my reference photos posted here on January 2nd and 3rd. I have been working on the foliage, which is the hardest part.  But today, apart from adding a little yellow to the leaves, I decided to concentrate on the hillside.  I put down some yellow-green, but it probably won't be the final color.  I used some darker green to begin to establish shadows in the foreground.
