I'm not crazy about the unfinished look on the southern elevation, but from afar that is one of the better views. This thing takes on a sort of optical illusion effect where it looks like a flat wall. The southwest elevation even enhances the effect, since the facade angles away to miss the capitol view.
On Gensler, I don't blame them so much as I do modern architecture in general, which has become pretty boring while thinking it's edgy and cool. Sure, there are some sleek buildings out there, but just look at that photo that Urbannizer just posted. Those new modern towers are every bit as boxy as almost anything from the 80s, and even the 70s. They even have flat roofs, which, we generally did NOT have during the 80s boom. I'm not saying I want a Gherkin building boom, just a little more variation. Less slabs, more shape and *gasp* setbacks. Residential towers benefit most from being boxy, though, as it assures you can have rows of balconies wrapping the building.
On the railings, they'll all have glass on the south elevation. Just refer to the rendering.
