My original design has the unfolded cityscape in a squarish block on a mostly flat plane, lacking depth and the impressive appearance I intended.
Directed to look at the Disneyland castle for reference, this has a much more grand look with numerous towering spires and a 'completeness' about it that has all of its elements fit together.
The triangle shape it forms, thinning as it reaches the tip of the central spire, is a good reference to follow, containing most of the elements in the central area and including much more height within the overall shape.
My original design already featured spire-like structures that are its key parts, so keeping these but adjusting there positioning and connection with the rest of the structure will hopefully achieve a much more impressive form that will illustrate my idea effectively.
Some other images I found that have a similar spire structure or interesting design.
