Remember that Thanos is drawn in a comic book where characters aren't drawn in profile. They're always in movement.
The vertical in the middle of the torso will help the artist establish the front of the character. The horizontals would be drawn in circles that will help define volume when in perspective
Drawing characters isn't just about what looks good but what's iconic.
