Viewing it from the Zilker Clubhouse. The tallest tower is farthest south. The southern edge of the tallest tower would be just to the right of the Four Seasons Hotel here. It would be well to the left of The Shore, remember, the Hotel Van Zandt will be between The Shore and the tallest tower in this development. So that gap will be at least partially filled in. I used Google Earth to see where it would sit. The tallest tower is on that lot north of that small apartment complex that zigzags through its lot.
I wasn't having much luck trying to superimpose the new rendering into my photo. The towers also need to be "mirrored" so that the tallest tower is farthest to the right (south) in the "image".
