Actually, it's not bad. Let's consider the alternatives. They could really be awful. Austin has reached a point where buildings between 400' and 500' may not me "architecturally" wowing or pleasing to the masses.
The city has reached a new level of architecture - which is good. It's no where near the major architectural hubs...but, inching closer. As the average height gets taller, we'll see the taller proposals have more daring designs. The ones in the middle (400'-500') will probably still be average because they will be hidden (or end up being hidden) by/within the taller mix.
Hey...this tower is still one of many being proposed or built that exceed my original home town's pride: Frost Bank Tower (at 29 stories and 386' tall).
