Returning now to a 2H pencil, begin to divide the left section of the tree into smaller shapes. Just as we did with the top section of the tree, these smaller, round, oval-like shapes should represent individual groupings of leaves and branches that are clumped together. You might find yourself dividing your first shapes into even smaller shapes. Again, these lines can be very loose and rough. In the image below, you can see how I did this for the top portion of the left section of the tree.

Keep drawing circle and oval shapes that roughly represent the clusters you see on the reference photo. Make a mental note of where open areas exist, showing more sky than leaves. You can also put a cluster shape or two in the foreground over the main trunk. Just make sure to eraser the portion of the trunk that is hidden behind the cluster.

As you finish dividing the left side of the tree, sketch a few long, narrow shapes to indicate some of the branches sticking out along the bottom edge. These branch clusters will have leaves as well, but they are more separate and distinguishable from the main clusters that are closer together.
