It's okay by itself. I like it more than when I first uncovered it. In someways it's better than the old design. It's more consistent with itself, all of the columns use the same industrial motif since they removed the cylindrical stringers. On the other hand, I liked the X's, and would have preferred they ditched the corner braces instead. I was never a fan of those, in any of their 3 configurations. But I think this will work out well in the end.
I like that there's a tiny gap between the braces and the glass curtain wall. You'll be able to go to the corner of the building on Church and look up through a 6" gap all the way to the sky. It's not something that looks good on a render, but will be cool in person.
However, I haven't put this model in with the other buildings yet. The key is how it will relate to Tower 4 and Tower 2, and the impact of the height reduction on the overall massing.
