Is a 370 word supplement frowned upon?

My supplement for Cornell Engineering is currently 370 words and the requirement is 250-650. Is this too short? How noticeable would it be if I left it as it is? I feel like it’s fairly well written and I used specific details about Cornell and some personal anecdotes which (hopefully) show that Cornell is a good fit for me. If I need to add more stuff to it, I could, but it would probably be pretty generic and not as specific to Cornell. Should I leave it or add to it?

(Procrastination at its finest… It’s due in less than 7 hours lol)

If you said everything you needed to say, that sounds good to me. I’m sure adcoms will appreciate the brevity.
