Yeah, I crosser through it today when I began the Skypiea volume. I thought they wouldn't show Alabasta anymore after the end of the previous volume, but they made a chapter dedicated to harp in some further details. I remember an interview with Oda saying he initially planned to let Pell dead, but a girl crying over it in a story he went to made him change his mind.
This is a very well made and nice looking panel.
This part with Bellamy is one of my fav ones in the whole story.
