Killing my darlings

I learned a new phrase this week. ::points up:: That's what I'm doing right now. Well, actually, right now I'm blogging about killing my darlings, because actually doing it is too hard.

And of course, my productivity has plummeted since school began. Hopefully I will reach some sort of equilibrium with that soon, and be able to be at least as productive as I was last spring. I've got too much interest in this book for me to fall off the face of the earth now.

I'm contemplating doing one of those dreaded mirror-gazing scenes. Mine would be different, of course. I'm not doing it as a cheap way of giving you a full visual without breaking POV. Nothing like, "She gazed in the mirror on her way out the door. Her long, brown hair framed her green eyes and freckled skin, and rested on the shoulders of her green turtleneck. 'Too fat,' she thought disapprovingly, despite the fact that she weighed barely over a hundred pounds." But I've killed the scene in which I established that Chris looks young for his age, and that's a fairly important plot point. So I'm thinking that he can be annoyed over a scene offstage, just before this scene, in which someone told him he looked like he was X years old, where he briefly examines his reflection in a car window, wondering if it's really true, and when it'll stop being true. That doesn't seem quite as egregious to me.

On the other hand, in a prepublished author, I'm not sure it's a good idea to even skirt by a cliché. Will editors and such be paying attention to the nuance, or will they say, "Ugh, a mirror scene. How trite!" and toss it?
