For those who haven't finished yet, I advise you finish it off then have a look at the story as a whole to find weaker areas that could be chopped out.
Sometimes, you shorten a story as much as it will go and then it can take something 'deeper' like a direction change. Maybe demote a main character to a supplementary one so that you have one less thing to worry about, etc etc. Cut out one scene entirely and lengthen another one... you get the picture.
