The photo is beautiful. There is however a small amount of purple and blue color fringing on the edges. It is more obvious on the window area of the structures on the lower left of the main building. However it is also on the main building. To see these you need to zoom up to between 100 and 200%. The noise reduction filter plugin in Photoshop does a good job at removing them.
I like it as is (except for the fringing), but I observe that the moderators likes it when the images have a little warmth added. So I suggest you do. That will highlight the colors a little more.
What was your actual rejection reason? Was it IP, image quality...?
