composition lesson--gardega method

Here is a composition lesson I learned by studying Goya.
I chose a still from Apocalypse Now as a reference.

(or vice versa) Where H intersects D1 you will find a perfect point of interest in your picture. Next draw a diagonal (d2) from top left to intersect D1 and H...
