Worked on cover and interior illustrations
I worked on cover and interior illustrations for “Failure Mapping” (Nikkei BP).
This business book introduces a framework that helps readers to visualize and organize their failures and use them for future improvement.
Even though it was a challenging request to personify “common” and “rare,” I depicted them simply as characters using a circle (familiar shape) and jagged shape (less familiar one).
Using characters makes the contents feel more approachable and engaging.
