So Pyke's visuals are a bit off.
He's supposed to be like a vengeful ghost, right? But he looks like a normal pirate in game, with glowing eyes. In his teaser / splash, he's underwater, and it gives him a ghostly look.
What if you just made it look like he was always underwater, since he drowned and all that? Would make him look more ghostly, would darken / desaturate his overall color scheme (to fit with his story and playstyle), and I think it'd look better overall.
