Yeah it all ultimately depends on the ratio of the distances to different parts of the subject.
Take a headshot from a foot away, and his ears might be 1.5x that distance away. Take it from ten feet away, and now his ears are 1.05x the distance. That makes their size similarly shaped too. Sometimes called compression, as in compressing the foreground and background together.
