Unique composition with the two levels of bricks in this shot. Detail level is good.
Shame we don't have all the time in the world to wait until the weather/sky conditions are right. A darker sky would have helped.
If you have Photoshop, one way to darken the sky a bit would be to go into the selective colors, drop-down to the white and move the black slider over and watch what happens. All legal as it is doing to all the white in the image.
Leveling the horizon would be helpful. Also a different angle so that the building and the white sky don't occupy an almost equal space. Nice and sharp, and good detail on the bricks.
