Title basically. I tried to underexpose the shadows severely to make it look more the silhouette, but that just made it look even worse. I suppose the only way to get better pics is to find a better location. But I would appreciate if someone can give me advice on any other tricks I could use to make the sky look better and take focus away from the urban hell

So I dabble in long exposures and light painting photography.
I think you can get some pretty cool images by doing night photography with long exposures.
And maybe a little light painting.

Also when you don’t have great color options, why not go black and white?
It’s always a classic look.
My other favorite novelty photography is infrared. Though that can require a good infrared filter or a modified camera.
