Hey mate, nice job! I think though there is some miss match of the amount of illumination of the sky v's upon the facade of the building.
One thing I would say and we all do it. We strive for realism without enough consideration toward what the image is to do - sell the proposal. Whether it be for marketing OR for planning we are still trying to sell, therefore would a little more light flooding the view of the facade give a better impression? I'd say this regarding the camera angle chosen too, could it be more dramatic rather than showing all?
