I agree with Munley--go with whichever sounds better in the paragraph (usually meaning whatever's going to give it more variation). Also, it makes a difference if you want it to be a slower moment, in which case, go with the longer sentence, or if you're intending it to be more intense, in which case separating it into two sentences with the "ed" would communicate that better.
If you go with the "ed," I vote for separating them into two distinct sentences.
