There is consistent proximity throughout the logotype. The negative space forming the "N" makes sense with the name because looking at the logotype engages the audience when locating the "N". I also think the logotype font works well bold.
Interesting to see the evolution from sketches to final comps for this beautiful logo. Rafal Skalski / logo / design / initials / white space / negative space / identity / sketches / process / steps to creating a logo
