Well it does look like digital concept art first and foremost. You could say it's influenced by 19th-century impressionism (closer to post-impressionism). These works were always oil on canvas and the artists tried to convey their ideas without necessarily over rendering the image as you would with realism.

It's a good fit for digital concept art since it too is about conveying ideas quickly.

I hope this helps. However, you might have trouble finding free CC works like this depicting a modern city at night. I wish you luck.

I'm only familiar with Bloodlines 1 so all my ideas come from there.

Could maybe make a game where you run a black market out of the back of a van like Fat Larry. Or a murder mystery game where you as the Malkavian detective have to talk to the objects in the crime scene to solve the case. Or maybe a haunted house experience similar to Ocean House Hotel.

I am looking to join a team but if I end up going solo I'll probably do the haunted house idea since it'll likely require the least amount of code to get working, letting me focus on the assets instead.
