I found this render of some South American building concept that slightly resembles the current 1133 Melville design...
With ours the angles aren't as extreme but it is cantilevered in a similar fashion and has a sort of slit cut out that wraps half way around the tower 10% below the top or so. Ours also looks more stubby as its likely not nearly as tall as this one is meant to be.
From what I've seen of ours I'd take it over this South American one (save for the difference in height). I have no idea what the curtain wall is supposed to look like for ours though.
