I see the rating system in Landscapes and eyecandies is a bit different from your typical map. So I'll rate it based on my feeling of it.
What are we looking at? Several empty, crumbling ships, grounded far in on a rock outcrop. The rocky islands bid little to no hospitality. You can't even place the keep. Indeed, except for a tiny patch of growth on the teeny weeny tip of one island, there is nothing there but cold, hard rocks.
It's kinda the same way with the story. We have no explanation for why those boats are stuck inexplicably there, with not a soul on them.
In its own way this is rather creative, leaving to the imagination of the viewer what happened.
All the same, a story would have been nice. Some troops that could fight against each other from the ships would have been nice. But the mystery of why these ships are barren gives it a creepy, mysterious charm to it. 3.5.
