Dragon Ball #42: Bye bye Dragon World

The ending feels very emotional and fitting, but I wonder what led to this particular choice. Was it planned from the start or a later decision?

It brought back so many memories of previous adventures, but also felt like a fresh take. How did others experience the balance between the familiar and the new?

The art style has always been iconic, but I noticed some unique touches here. Was this volume used to try new techniques or styles?
