Some more I designed over the last few days. Up to 27 structures now, shooting for around 100 eventually...
John Hancock Center is a similar build to the official model but instead of stacking plain bricks I used side-studded bricks with plates on the sides to add more of a textured look, plus I made the antennas offset in height as they are on the real deal and it's accurate to the scale of my other models.
Canton Tower was fun but it took at least a half dozen iterations before I found a build method that worked for the overall shape.
