Very interesting architecture, however, the photo itself seems a little flat. Perhaps you could move the black spot slightly to the right and the white spot in to the left a little. Often this will give an idea of what can be achieved to make the scene more dynamic: finer tuning can then commence. A 3x5 crop might work well here and really accentuate the shape of the building.
