I really like the angle and agree with @MikeFewster on the feeling of weight. However I think this can be done in (at least) two very different ways:
1.) emphasize the golden/sand tones and in contrast to the hint of blue in the windows and sky and make it shine.
2.) emphasize the effect of weight and pressure
I've tried both and feel like the second one is probably done best via a black and white conversion with strong contrast and highlighting the blemishes on the surface.
However comparing them I liked version one more, where I tried to make this building shine. It doesn't lose its weight of course, but it still appears (at least to me) more like a symbol that way.

(I've also straightened the lines a little bit)
