What don't you like about it? Knowing that would make it a bit easier to give advice.
Most I can say at the moment is that a lot of PWPs are thrown into one place. There's the area where you have the pyramid, Sphinx and Stonehenge close together, and further south there's a jungle gym with various other PWPs placed nearby. I'm not sure what other people think about that, but I like to space mine out a bit more.
The path you've laid out is neat, but kinda confusing. At some points there's a dead end, or it's confusing about where the path will lead.
