1. the cropping: I think you should show the whole entrance instead of cropping the roof.
2. the view. Either raise your camera alot higher and make an aerial view, or lower it to eye-level. Now youre somewhere inbetween and it doesnt feel right (imo).
3. The light: The sun is behind the camera, which always makes it difficult to make an interesting image. I would move the sun alot either to the left or the right. That way you will get funkier shadows.
