So now you have the bones. The rough draft is done and you now have to go through it and make it shine. Where to start? I'd recommend you start where you feel drawn to. I normally read through the manuscript to see where I'm weak but I can't help but make corrections as I go through. I ask myself questions:
Does the scene flow?
Does it move the plot forward?
Does the dialog make sense?
Is there enough description or too much talking heads?
Does each scene end with a hook?
I might go through my manuscript three or four times to catch it all. Now I feel I need to explain this. I did try to cut down the amounts of edits needed but found that didn't work for me. I need to do this in stages to get the best story I can.
