Well, I've been intrigued recently by Hair Razor, watching the episode 'Chindred Spirits' from Fairly Oddparents. I've started off by using what little reference material I had to construct basic 5-minute sketches of the character to get used to her appearance, movements and personality.
After that, I will begin to make a more detailed and more carefully thought out sketch , starting with a miniaturized version on the top left to establish a pose I like and then working on a larger version next to it.
Which I then finalize with cleaning up and making a witty dialogue coupled with a story. I believe a good story always makes a good picture.
