Helmswoman help

Hello there. I'm fairly new at Digital painting, although i have made traditional art for years.
I have currently an unfinished illustration that i had planned but somehow now i'm blocked in a series of issues.
As you can see it's very unfinished and i would like you guys to help me if you can with:

- How to make decent futuristic buildings with lights ( think of nighttime Coruscant from star wars ).
- How to make clouds on top of the buildings vanishing point
- What reflections and shadows i'm missing on the character ( the only part i'm considering finished is the vynil.like suit.
- The orange armor needs a lot of work but should i make it new or weathered? and how to make reflections?
- The lighting on the neons is also unfinished, plus the "eye " of the helmet. Any thought on it?
- the red rectangles u see up there are flying vehicles seen from below. Where can i get some references for them, please?
- Lastly, since the picture has dark tones, how can i make the figure more distinct than the background so it has more importance?

I know this is a lot to process but i would appreciate any help you can give me.
