If Oda would draw the volume 25 today (the volume where we first get introduced to Whitebeard,Blackbeard,Gorosei,etc.) he would never draw them like he did,he would probably silhouette Whitebeard and the Gorosei at least,and maybe also some members of the BB crew too. And we would see Whitebeard design probably only in Marineford. But that volume is nowadays remembered as one of the most epic volumes of the story,so this proves the fact that he doesnt need silhouettes to create hype. Just shows the damn designs of the characters,Oda!
