A very big improvement.
Your best by far.
The effects are nice, as well as the colors.
And I like how you went and manually brought out the lights in the bg, makes it bolder.
Try to work more on lighting by adding light where light should be. Get a soft brush on Soft Light or anything that looks good.(I prefer screen) And add a blue light the the sides of the focal where the city's lights should be hitting. Make sure not to go overboard, seeing as it's all behind it. This will also increase the blending of the focal.
I'm unsure what to look at because of the depth. You blurred the object to the left more than the building in the center, so i found my self looking at the center right off the bat. I couldn't really make out what I was supposed to be looking at until I saw the little sister and then I saw the whatever those things are called
It also looks like a WIP due to the empty left side. I would suggest adding more effects and tie the whole piece together.
