I discovered David Kibbe’s 13 Body Types Theory from a YouTube channel called Ally Art. Although I am still learning about this theory I will try my best to break it down. In this theory it explains how the human body consists of masculine and feminine energy.
To simplify things, I will refer to the feminine energy as Yin and the masculine energy as Yang. Yin and Yang can manifest itself in many ways. Such as our bone structure, vertical lines, facial features, height and the way the flesh covers the bone.
