Neketaka as shown on the game's main screen looks gorgeous as hell.
But inside, due to the over the top camera angle, it looks boring.
On top of that, it didn't have many areas with beaches and town both. Queen's Berth had a dock but the water component was very small. There was no islet as well.
Brass Citadel was extremely tiny as an area, with obviously no beach areas.
Argos, from Clash of the Titans 2012 is what I deem, to be one of the ideal ways of representing an island city against a mountain, with so much colors, mystery (on the horizon) and undiscovered areas.
