I wonder how much actual freedom he had to do anything interesting here. The existing roads are dull, and the section of land given is so long and narrow that it feels like there's very limited options for what you could do with a track that would be appropriate for F1 cars.
I'm not a massive Tilke fan, but I think he got handed a booby prize with this one. I can't imagine that he was given any choice to select roads around the area and took that. For example, you could almost certainly do something more interesting with the roads around that big circular sport stadium complex to the north east.
