In junior high school (7th-9th grade, 12-14 years old, 1981-1984) I learned how to draw bodies (though bizarrely proportioned), and 3d 2-point perspectives. As any junior high boy, I was into sports and sci-fi so that is what I drew. I couldn't yet draw faces at all, so everyone I drew conveniently wore helmets. The following images are presented in chronological order (or at least as best as I can remember).
