Seeing the forest AND the trees

I was looking at a drawing book today on the bus during my morning commute. The guy next to me is covertly checking out what I'm looking at (I know, because I do it too when someone next to me is reading, so I know all the "signs and symptoms"). Finally, after seeing me flip through several pages on how to draw really great trees he says, "So, are you learning to be an architect?" -- Lu
