I recently turned my pages for The Price Of Jade over to a friend for review and she loves giving my pages the red pen treatment. In fact, she gets so giddy about the red pen treatment of my stories that I often refer to her as my abuser. Believe me, what she does for me is far from abuse, in fact she is more of a life saver.
Seeing red excites me because I can see all of the things that I am blind to as a an author. Once I know where I am lacking, I can bolster my story and improve the narrative for the audience who will eventually receive the finished product. I can't always see where I am going wrong, as I am obviously biased when it comes to evaluating my own work. For some, criticism is intimidating, but for me, it is a necessary tool for improvement. Of course someone welcoming criticism expects it to be constructive, so a person who is doing a proper critical analysis must also recognize and comment on what a Writer is doing right in order for it to be constructive. My best teachers always included remarks either in the margins, or at the end of the papers I wrote to let me know where i was on the right track, or where I was off; it was never just about marking things wrong like punctuation with no feedback. I also saw passages underlined with the word "good" to show what impressed them.
The red pen is a lifeline for those who require guidance, so be a guide instead of an executioner. When a person puts their blood on paper, they deserve honesty in return; but you need not be cruel. Blood is also a sign of life and it is red. What would you like to see more/less of? What grabs you or makes you snore? Is the character compelling, and if not, what would make them so? Do you need more background or more explanation of a scene? Go ahead, leave your mark for the better. Let the ink flow!
