Nice work. Composition doens´t fully work. May be its because the empty area of the sky or the slightly unbalanced lines in the bottom. There are slight chromatic aberrations in the columns (that´s a camera flaw but it can be fixed with PS), and the white line in the upper area can be cleaned for no distractions. The cropped columns also break the composition. If you break the columns then I think it would be better to crop when the mountains end so no void areas will fill the frame. Good exposure!.
