I explored around here yesterday. There's lots of artistically arranged steps and levels which someone could have some fun trying to represent in the data, but I see you've already done the northwest corner viewing platform which is probably the main thing.
I also noticed there'll be some now public toilets at the lower level, quite near where this note is, but they're not open yet, so that's one to keep an eye on, along with the finishing off of that strip of building works.
