Not gonna lie, I forgot I had been reading this series until I came across something a few weeks ago. So, I don't exactly remember what happened in the previous volume, but most of it came back once I started reading this one. I appreciate the way this breaks down the art process, thinking about composition, theme, and just general art technique. 

Yamaguchi also includes other art pieces throughout the manga, mentioning sources in the author's note at the end. This just celebrates art in the form of art, and I just think that's so cool. This is the end of one story arc, and I'm excited to see where it goes next.
