How I plan my scenes

Last night, I did some sketches for a very important scene in a story I'm working on. I would upload the sketches, but they are rather bloody therefore a bit disgusting. I still like them, but I also realized that there would be no survivors if there was that much-- erm, blood. So, I'll have to change that scene around. But it'll still be good! Oh yes! And it'll make so much more sense.

So basically, what I do is start sketching/doodling things from a scene. Sometimes it peoples faces or their hair or their hands. Usually, it's a good reference for me later. That's why I have a file box full of sketches. Good reference points.
