Strongly disagree. These are 3 sets I just generated with v5 using the following simplified version of your prompt: "interior of a future-brutalist megastructure, comic pastel style, sci-fi robotic architecture, 70s".
Specific words and phrases that accurately translate what you want into the latent space are way more important than complex prompts.
If you've played around with MJ much you'll know what I mean. Some words and phrases overpower everything else in the prompt. I've found that good MJ prompts are very vibe based.
