Too consise?

I'm preparing a manuscript to submit to Nature. In addition to a low acceptance rate (8%), they have severe word limits. The 'main text' should be "about 1500 words" excluding introductory paragraph, references, methods, figure legends, etc. It is the intro, summary of results, and the discussion all in one. My main text, of which I now have a complete but not final draft, is 1138. It was not hard to make it this short. This is just how long I wrote it. This of course makes me think that there are all sorts of vital things that I should have said but left out. I will think about what these might be after my wife and daughter are asleep.
