Don't forget the Barton Creek Square Mall vantage point as well (north/northeast parking lot). The view encompasses pretty much the entire skyline, including the University of Texas and Capitol complex clusters. That view has been popular since the mall opened nearly 30 years ago. It is located at the northwest corner of south Mopac Expressway (Loop 1) and Loop 360 (SW Austin).
This is a partial view I took last month (not including the Cap or UT)
