"Where there is perhaps a province in which the photograph can tell us nothing more than what we see with our own eyes, there is another in which it proves to us how little our eyes permit us to see." ~Dorothea Lange
The sky here is a gorgeous blue! However, there's not much of a skyline, so not really much to look at. Also, you can see pretty bad distortion that give away where each of the three photos were. The outside 2 are tilted in and down in relation to the center one. Using a tripod to take the pictures should fix that perfectly.
The light seems a little harsh at that time of day. It looses some of it's detail. Maybe the same shots at twilight or dawn would give more textures. Keeponclick'n
