Christmas at Creighton University

Can Someone please tell me what I could have done to make this image

better?

Usually it is best to capture more of the trees and surroundings. That means shooting when there is more natural light, sometime in the twilight hour. Underexpose for the natural lighting by 1 - 2 stops (don't meter the lights). This will make the picture look entirely different, and the composition will look more like what you visualized.
