Nice to see the image free of people, but it leaves it somewhat disassociated with the ground. In cases like this I usually just accept that the people will be in the image and use some of them as a focal point to counter balance the architecture. A wide angle lens under these circumstances helps a lot to create a sense of grander of the architecture and also to reduce the human clutter, because they get small very quickly with distance, The structure of the architecture has come out well, but the sky seems a little false, but then I can hardly be accused of not tampering with my skies!
