For what it's worth, I did the exact opposite and I'm getting really anxious about it. I started with a 1,000 word SoP template and then trimmed it down depending on how each school framed what they were looking for in the "Please explain...." prompt on the application. As a result, I didn't really give much of a narrative about my choice to pursue grad school, didn't really propose a project (more just said: here are the questions that motivated the thesis I just wrote and I want to go to grad school to work with a POI who is motivated in their work by these types of questions), and didn't really expand on any of the stuff that comes when one deepens that narrative/proposed project side of the application (e.g. detailing why you really are a fit, showing that you are more well rounded than some vague research interests).
My point would be, I guess, it's a trade-off. There might not be enough in my short SoPs to distinguish me from all of the excellent candidates that apply. And the only way to remedy that is perhaps by risking what you risked--namely, giving too much detail. The SoP is such a tight-role walk! I guess we just have to wait and see what happens. The best is probably just to stay calm and wait, though that's definitely hard to do.
Best of luck!
