Which manga artist has shown the most improvement in their art style? Comparing the first chapter to the latest

I've been seeing a lot of manga artists posting comparisons of their art from the first chapter versus their latest chapters on Twitter recently, and the progress is truly astonishing.<br><br>Here are a few who I think have improved the most:<br>1. Eiichiro Oda - "ONE PIECE": The early lines were so simple it's hard to believe.<br>2. Kohei Horikoshi - "My Hero Academia": The action sequences have become increasingly fluid.<br>3. Gege Akutami - "Jujutsu Kaisen": The battle storyboarding in the mid-to-late stages is incredibly dynamic.<br><br>Which manga artist's improvement surprises you the most?
