Eagle Project Progress

Today's progress.  I noticed immediately after posting the previous days work, that the two branches in the upper left were very small and frail looking which made me feel the whole thing was too delicate and not stout enough to hold an eagle's nest.  I have increased their thickness and now it reads as a very substantial tree.  The entire time I worked on the branches and nest sticks, I am keenly aware of where my lightsource is coming from.  I am trying to keep shadows running in the correct direction.  It really helps that I have some very good reference photos of the nest and birds. I can draw without worry, since the lightsource is the same throughout the references.
