Niuroda Shading Studies

Niuroda is a tangle named and deconstructed by Tina-Akua Hunziker, CZT. According to her blog post, she was inspired by a postcard sent by her aunt, and since she is a "Capoerista" (a form of martial arts very popular in my home country Brazil), she named it after Capoeira's typical formation, the Roda. The essential structure of this tangle is made of three or more concentrical circles, and when shading it gave me the impression of working with three donuts, placed inside each other.
