After reading 'DiddyDave' I can see where he is coming from. However with my untrained eye I felt that I liked the 2nd shot(corrected) I guess because it portrays the building as we would assume it to be. 90' angles etc., and so feels right. However, as we assume that to be the case, then when viewing the first shot, it's as though the image sides are not true and the building is...as who would build anything with such angles so the crop would be askew.... visually. Whether you could compensate for the slight asymmetric aspect of the second shot, by a different crop, possibly. That aside, I feel you have captured a magnificient building well.
As I say, a novice opinion.
