Next will come the long job of further drafts to get it into shape before submitting to literary agents - another long job in itself.
But, for anyone at this stage of the writing process, be it 1st or 2nd draft, here are a couple of books I've read that I think would be useful to you.
The first is a book by John Mullan called How Novels Work this link is to an updated version of the one I read so there might be more handy hints in it than the 2006 version. Well worth a look for any novelist.
The second is by Renni Browne and David King, called Self-Editing For Fiction WritersAgain, lots of really useful advice
