That wall can work really well as long as they get the ground floor design right. From how that rendering looks, it has a very contemporary artsy vibe to it that is part of the whole picture with the garden and art installation. And I think that is what the architects were going for.
Also, very crucial on the exterior material used, they can't cheap out.
Interesting to see a single loaded proposal, not often you see buildings, especially towers like that. But given the view is where they will make their money it makes sense as a design choice. I don't think even the highest quality can save that blank wall through. It definitely needs some horizontal elements and massing variation to break up the wall somehow. Very crude example:
It would also likely help to have a pedestrian entrance on this side, and you could use the entrance atrium in a way so that the building doesnt completely face away from the street.
