I'm really glad to see some movement on this building. And while I'm happy to see the Warwick (or at least it's facade) has been preserved, I don't see the original renderings anymore so it's hard to say if this is better or not. If I recall, it's mostly similar but I remember in the original design, the Sansom Street facade being a bit more interesting but the Walnut Street facade being a bit less interesting. Is anyone able to post the originals? I went through the first few pages before giving up.
For sure though, the best thing about the redesign is that it serves as evidence that they've been working with the neighborhood which leads me to believe that this has a realistic chance of happening.
Overall, it's a good design. Very tasteful, the height is fabulous, and it will offer the Square a bit of a architectural diversity. That being said, it's not particularly jaw dropping, like say Mandeville Place or the Bridge. And for this location, I think that's a reasonable expectation. Personally though, I'm not disappointed, it's still a very nice tower.
From a viewpoint, this tower will look best from 76. After Spring Garden, it will be front and center:
