Well now, this would probably be the tallest building between Houston and Los Angeles. Somewhere around 700 feet or so. It would be more than twice as tall as Midland's tallest building now, the 330 foot 24-story Bank of America Tower. It might also be taller than the Austonian in Austin, so it would probably be the tallest building in Texas outside of Houston and Dallas.
