That's just sad, no originality at all. Treading down the same tropes, alcohol - uncertainty - etc. At least there's a chance to move the plot really far under these circumstances. Now we see why 0.190 takes that much time - lots of NPC's. Even for his rig rendering 20+ individuals is a tough task, fan artists usually don't create scenes with more than 5 characters at once.
His two NV-Linked 3090's should be able to render a scene like that in fairly high quality, though the second screenshot does look slightly pixelated, so maybe it is indeed pushing the limits of their memory. He should consider upgrading to whatever comes after the current 4090 flagship (probably the 50 series), that would likely solve any issues with even massive crowds.
And concerning the time it takes, well, if the club scene was rendered within the past few days it would certainly not explain why everything before that took as much time. And looking at that render, many of these characters are in premade poses. Now, he's obviously gotta dress them, make everything fit etc. but once that's done he should be able to progress fairly quick unless there's plenty of renders showing the crowd with people in different poses, lighting and whatnot. We'll see!
