Thank you for the feedback, Tom.
About the blues: I actually de-saturated the top of the sky a couple points. As for the blue lights on the buildings, I didn't mess with that. Although I have decided to pull back the saturation on the tops of the two building on the left (I'm very happy with the top of the building on the right). As for the stadium, only the right side (which you see) and the left side (far side, out of view) are illuminated with blue lights. What you see on the side of the stadium is just blue light spill from the exterior lighting. The seats in the stadium are indeed blue but we can't see inside the stadium at all at this angle.
The black across the bottom: You'll notice a row of trees in the foreground. Just on this side of those trees are a couple expansive parking lots. I really didn't like how the light spill on the parking lot pulled the eyes downward so I opted for pushing that area to mostly black. I agree the dark bottom is a heavy anchor - I just preferred it to a blank slab of asphalt.
