But I like to keep things pumping so, if I'm cranking out a novel draft, one of the things I'll do on a write-off day is draw stuff from said draft. And my first point of entry will be character portraits.
I'd recommend it to any writer, no matter your artistic ability (as you can see mine's so-so at best). Firstly, it keeps your brain on the ball manuscript-wise. Secondly, the process of drawing your characters brings you closer to them. It's an oddly intimate process: you may think you 'see' your characters, but what is the stance of their frame, the arch of their neck? How, indeed, do your characters pose for a portrait?
No, the greatest benefit I get from drawing characters is the slow reveal of a face I never expected. New layers of my characters' personalities are excavated in the drawing process. That can only help the manuscript. At the very least it can't harm.
I'll most likely do update posts as I draw more. I may even invest in some pencil crayons.
