That looks incredible, dleung. I'd be interested in seeing how you refine that.
I am unfortunately going to be bowing out of these competitions for now. I recently got employed full-time and I now have CAD as a regular fixture of my job, so I am taking a break from doing it recreationally.
I did have a design half-done though. It has two separate cores with elevators that would meet at the top in an arch. I was also planning to create a new transit terminal as part of the building podium. My big mental block was trying to find a suitable cladding design for it. Maybe sometime I will finish it.
