Thanks. I picked this spread to show you because I thought it at least fit the 'vibrant' description, even if they're not all modern or cyberpunk! But there are some other great creators here and hopefully some of them might show up and give you options.

Since you're on a deadline, feel free to email me or Discord message me (all in the signature graphic space) with more information and inspiration to capture your campaign setting plus the character of your vampire who runs the nightclub to give it personality. There's nightclubs, but then there's YOUR VAMPIRE'S NIGHTCLUB and it's important to me that we capture that in the art.
