Alright this is my entry (please excuse its suckiness), It's my first time entering a competition and my first time trying to make a noble gas giant, that's what the lights in the sky are. Argon, Xenon and krypton light up when in contact with an electrical current, so what happens when there's massive storms nearby?
I was originally flooded with ideas about a large futuristic city, abandoned for thousands of years, with all streetlights still on, but completely uninhabited. Sadly i could only make it work on a pen sketch.

Your writing is coming along brilliantly as well!
