You have a tendency to use passive sentences. These sound cold, and too many will repel the reader.Well, mine is:
Eight-seventeen in the morning and there was one less towel on the towel rack than there should’ve been. Normal observers would not have noticed, but Sophie did. She didn’t bother to look for the missing towel, for there it was, on the floor.
Third sentence I feel is lacking. But hey, that's what drafting is for.
Try cutting it all down so that you're giving the reader the benefit of the doubt. I understand that you want your words - to reach the word limit - but it's better to have something amazing, right?
At eight-seventeen in the morning, there was one less towel on the rack. Sophie noticed. There was no need to look; it was hung up on the floor.
I didn't make it perfect, but try comparing the rhythm.
