Looking good! One thing I really like about this map is the imaginative shapes. It's recognizeable as Manhattan (probably once it's pointed out to you) but it looks like somewhere else altogether - which is as it should be with a P-A map, especially a far future one. You going to have any ruins? I guess that, after such a long time, the skyscrapers would have mostly converted into hilly terrain rather than anything recognizeable. Might make for some hills at the tip and up just south of where the park was located. I guess the part would be nice low-laying terrain, actually, since it's surrounded on all sides by some tallish buildings.
