Editing is about information first, then style and characterization. That's how I would evaluate this:
1) Information: is all the necessary information there for the reader to follow the story? Did you have the plot in tact? Are the secondary characters offering the right info at the right time?
2) Style: have you stripped the writing so completely that there is nothing left of your own personal style to make it distinct from other writers. I'm not talking about purple prose or adding in tons of descriptions, but are your particular 'flavors' well balanced in the word choices, sentence constuctions, etc. For instance, I write lean, but go back in and flesh out some of the sketchier parts--with lean details. (Meaning they didn't exist at all before.)
3) Characterization: I recently rewrote a paragraph for a secondary character because the dialogue could have come from anyone and been said to anyone. Are your characters inhabiting the world you created for them? Do they refer to one another and their histories outside the written pages? Do they reference past, present and future events to give that sense of being in a legitimate world?
Here are the two paragraphs I was talking about:
Original paragraph:
His father looked at him, considering.“I still don’t know if you got what it takes, boy. It’s a cutthroat world and I’m not sure you’re made of strong enough steel to handle this company. It might be better if I sold it before I’m too dotty to run things anymore.”
The Rewrite:
His father looked at him, considering. “I still don’t know if you got enough of a backbone, kid. These men don’t play at business, they are the business. This won’t be like your playground in college and not like those architectural people in New York either. I’d start paying attention, learning how they operate. They don’t say keep your friends close and you enemies closer for no reason, son. Now if you want to see someone born for this business, take a gander at Cody Graves. He knows how to take charge, make people sit up and pay attention.”
Now, the writing itself might not be the greatest, but you can see in the second example that this dialogue is world and character-specific to this particular novel. Hope that helps make sense of what I'm talking about
And I do hope that this information helps you solve your dilemma
Warmly,
Jenny
