Nice pics! The second is my favorite, and i agree with bigtwinky. I can't believe you cut off the reflection in the water. I think the symmetry of the picture could have been insane had you got the tops of both buildings and centered the horizon. With that being said, still a great shot, maybe zooming in to balance off the picture may add another dimension to it?
The reflection in the second my be impressive, but a big damper is the fact that the reflection of the tallest building with the green top was cut off. So sorry to say so, but that little fact throws the photo into the "good attempt, but"-folder.
