It looks like they're trying to call out the best of Telus House, but without the compositional clarity. I understand why the Gardiner side can lean to being a bulky hulk, but not the rest.
One aA's strong calling cards is their attention to detail, in finely tailoring things. Maybe they are not capable of properly conceiving engaging complexes of this size yet. ICE is alright - maybe the firm is currently overextended. Or they might be more comfortable with stand-alone buildings, where they have some contrast with their neighbours. I'd also like to see aA off this condo kick and designing places of worship, symphony halls, arenas, movie theatres and just about anything but another high-rise, to see how they'd do. But I guess that's not where the market is right now.
I'd say the base needs a radical re-think. I reminds me of the 70's Eaton's building in downtown Vancouver. The towers shown haven't engaged me yet, either.
On a side note, if there was ever a rendering that needn't show towers in a park, this is one of them.
