Alright, so here’s the thing; the reason there’s been so much “controversy” surrounding female mocs(this is not just something that’s come up lately- we’ve been talking about it on and off for forever) is that folks simply don’t understand how to express feminine features in their building. They tend to either overly express(even "sexualize) those feminine body shapes, or do what you’ve done here, and build an otherwise masculine moc- just to add on nuva boobs and call it a day.
From my experience, neither of these methods work out all-to well. The former comes off as unrealistic and non-beneficial to the character(not to mention, kind of creepy on the usually male moccer’s part). The latter, as you’ve done, really just exemplifies inexperience. It indicates that you don’t have a full understanding of what defines a feminine body; building a man and adding breasts won’t cut it(unless you have a very specific reason for doing so, but that’s doubtful).
All that said, I suppose my suggestion is to look at some anatomical sketches- visuals that show how female proportions work; from there you’ll actually get an idea of what needs to be thicker, thinner, etc. It can look feminine without having huge, round parts that say"look at me, I’m a breastplate". You should also consider that Lego hasn’t historically made any base builds that align well with feminine proportions, so chances are that you’ll have to come up with something on your own. The best thing you can do is get a reference and be creative.
