Remember, in perspective drawing, your eye line and the horizon line are one and the same. The horizon is always across from you, no matter how high up or low down you are.
Anything below your eyes is below the horizon line and anything above is above the horizon. Think of it like looking up or down with a camera.
Following note is a good summary of what we covered.
Absolutely one of my favorite drawing instructors, I have taken courses with Tony O’Regan at Emily Carr. Below are a few videos of his on perspective. If you go to his website, http://toregan.com/ you will find many.
