Backyard Tree, the making of a painting

We just moved into a new house in a fantastic neighborhood. Every morning, when I eat breakfast, I have a great view of this tree across the alley from us. I think this tree and its crossing branches has such a wonderful shape. I really want to try and complete a painting of it before the leaves come out for the spring.
The above image is a plein air preparatory drawing for an upcoming painting. I used a simple pencil and a white pastel pencil to sketch it out in my spiral bound, grey Sennelier pad.
