CONGRATULATIONS!
You have found the third of my secret pages! The rather large image you're looking at is from Color Walk 1 and is a collection of sketches Oda created for Fishmen pirates in Arlong's crew. Some you may recognize, some you may not. Interesting to see the different designs he started. Note his selection for Salmon and how that eventually turned out in the form of Shioyaki. Anyway, hope you enjoyed this! There will be more to come!
