If you're anything like me, the characters in your novel tend to change a lot. At first my female protagonist has long brown hair and blue eyes, then out of the blue, I began to see her as a girl with short blonde hair and green eyes. It gets monotonous because I just wish I had a picture next to me I could look at and visualize the characters, but if you're like me, you suck at drawing.
Now one thing I really like doing is playing MapleStory. Over the summer I found a MapleStory simulator called BannedStory which lets you customize your own character using any accessories in the game. I suddenly thought why not try making the characters in my story using this method. I did and it gave me something to work with on my rewrite. Sure, these are super-deformed anime characters, but with a little imagination it's not hard to imagine them as real people.

That's Timothy, my protagonist from last year.

And this is Amiil, this year's MC.
I actually came up with most of my plot and characters just by playing around on BannedStory. Here's how to use it.
1.
http://www.maplesim.com/app/2. Click "Start the Simulator"
3. Click "Start" button and wait for it to load.
4. Select "Character Layer" in the "Add new layer" dropdown box.
5. Use the toolbar on the left to add skin color, face style, hair style, and clothes.
It may help to be a little familiar with MapleStory, but it should be pretty easy to navigate around. When you have a character you like, just go to File - Save Image. You can save it as either a .jpg or a .png
