A bit more on the island mock-up, presumably that's how it's supposed to look like?

"Presumably" implies that we definitively know what it will look like.
What you've posted is an educated guess depiction of what the island could look like, which is fine but we won't know until we see the island completed with some pictures of it on the ground.
I see no reason to worry too much at this stage, just give it 6-12 months and by then we'll have a better understanding of its footprint and overall geometry.
