Hi. I hope you don't mind some brief constructive criticism and suggested VNs you could emulate. Anime Studio Simulator has a bunch of good points, definitely, but I'll just save saying those for last.
So the writing itself needs polishing, as is the balance between the simulation aspect and the story aspect.
In what way does the writing comes off as rough? It feels as if I'm being told what's happening, with little sense of pacing. It can be difficult balancing the story aspect with the stats-building and simulation aspect, too, but I've seen it done.
In terms of balancing the two aspects, I suggest taking a cue from Royal Alchemist by Nifty Visuals (stats raising for the MC and her students) or Rock Robin by Happy Backwards (band management, which is very close to this anime team management you have here).
In the Royal Alchemist, something happens in-between stats-building. I don't get to decide what, but I'm given options how to react to them. In Rock Robin, I could choose to have my band members practice, or I could talk to them, which has dialogue options.
I believe you can replicate those with Anime Studio Simulator by having the characters interact more with each other.
(I was actually expecting Yukari to have the option to bond with one of her team members, especially at the beginning, maybe look over someone's shoulder while they work or have an explicit one-on-one conversation with them (or one-on-two for the artists) with dialogue choices instead of just choosing "supervise" and all I see is a black screen, followed by the next scene.)
In terms of writing dialogue, you could take a cue from Queen's Crown by Agashi. The stats there aren't explicit but if you read between the lines of the dialogue choices, you'd realize that some responses show arrogance, some show compassion, some show objectivity, and so on.
In terms of making the stats feel more natural, you could take a cue from The Pretender's Guild by Minyan. Though it's an otome game, the romantic options don't always bring the MC closer to the romanceable character. It'd be good to observe how they take into consideration the context.
These four VNs are all on Itch, so you could find them easily. If you're lacking time, I suggest prioritizing trying out either Royal Alchemist or Rock Robin to plan your outline, then close-reading the dialogue choices in Queen's Crown to flesh out the parts of the outline that need dialogue. Except for Pretender's Guild, the three are demo's.
It seems you have a community following you already, I suggest making the most of that and improving your VN. For my part, the following are what I liked about Anime Studio Simulator. Good luck!
The art gives a good impression and no doubt commercial material. The colors on the character sprites fit harmoniously in palettes. The poses give me a glimpse of their personality. (Mayumi's taller stature over the others makes me think of how it emphasizes how she's rather naive for her age, Yuuko is clearly introverted, Sumiko may be the opposite of Mayumi.) The colors of the boxes containing "anime" and the text color of "studio simulator" communicate fun, light-heartedness, and, well, anime.
The story premise is also interesting, as others here have already pointed out.
