I recently tried out a technique from Andrew Loomis' 'Creative Illustration' called informal subdivision which is used to create a more informal composition to your illustrations. Below is the scan of the inks that I created using the technique.
I felt that it created a composition I wouldn't of created naturally but a couple of things didn't fit like the size relationship between the characters so I tweaked it after scanning and made the sizes more accurate.
I think with the tweak it works nicely as an image so I may well try this technique again. I recommend checking out the book and trying some of the techniques.
