I like the colours and structure of this image, the bland sky makes the building stand out well. I looks slightly skewed to me, which I suppose is a visual aberration but it makes the picture look unbalanced, which is a shame because it is a very strong image.
I agree, it does look slightly unbalanced. I am however fond of the lighting and the colour tones.
But I feel that the fact that the photograph is unbalanced takes a lot away from the impact that could have been made.
