I'm sure a lot of people will mark this down because, whilst it might have been taken at 4:35am, it wouldn't have made a difference than if it were taken at 2 in the afternoon..
In any case, I love the symmetry. It's eye-catching and has a certain 'wow' factor to it. I certainly hope it's a shot you had "prepared earlier"!
The background does seem a bit noisy, particularly toward the bottom.
7 from me.
A technically perfect shot and creative arrangement. Lovely colors and a "How did they do that?" element as well. Will be interesting to see how it resonates with voters. Only critique I can make is that your choice of backdrop, be it paper or whatever, has a pattern to it that gives the impression on very first glance that the image is noisy. Of course it isn't, but you may want to think about that for your next setup.
I feel like this image fits the word of the law, but not the spirit of the law. Nothing in this image tells me 4-5am. I completely believe that you took it in this timeframe, but the image doesn't make me feel anything.
Its a well executed image and so I will give it a nice score, but it will not be rated as highly as those images that also expressed the time frame.
