Wait a minute. What is that really tall pink line north of Frost Tower?
Also, the building south of Lady Bird Lake is missing from your list. I'm guessing that's Aquaterra? And you might want to update your rendering for Seaholm.

The Whitney Printing Tower may just be my favorite development under construction right now. It's not huge; it's just a solid project in a key area of downtown. And it's apartments, which makes it even cooler. The Gables Park Plaza Tower is definitely up there with it, though.
