Try drawing in one-point perspective. Stick with one vanishing point, don't worry about two or three. Think of it like a theater play, where you see characters in full with clear poses. Since you're looking straight ahead, there's no foreshortening, which makes it great for practicing proportions.

Do a few sketches and play with the horizon line, high and low, to get different drama in your composition. Lean on overlaps to create depth, and try to draw your humans in full. Please post your work in the comments below, I'd love to see them!
