I've finished up the leaves and most of the areas reflecting in the glass. The sepia color worked perfect as a base under the green leaves. I was able to get the depth I wanted, with less layers, by working over a complimentary color. I used ground pastel dust applied with tissues for the blue areas. Everything else is color pencil. While working on the leaves, I was able to take advantage of the view out my studio window. As long as it wasn't too late in the day, the sun hitting the leaves of the lemon tree just outside my window made a great source of reference.
