I'm really proud of this one -
Jeddah (Kingdom) Tower in Jeddah, Saudi Arabia!
While the building is far from finished, I was able to find a lot of reference material by scouring the Internet. I used artist renderings, images of physical models, floor plans, and elevations to get the overall form and proportions correct. I even found a video of a lecture where they were explaining the transition from the main tower to the spire, which was a complex feature to get right with how the three segments split just after the large, round observation platform about 2/3 of the way up.
I also used a site plan for the ground details and terrain around the tower.
