When developing the character i started on the head and worked on head and hair styles.
As can be seen in the image i decided a more shaped cheek gave a better image when taking an angled side look, and hair was less boring when spiked upwards on the fringe.

Once i'd worked out a rough headline i tackled the part of the characters head that looked weird... The eyes.
Whereas the straight simple lined eye appealed to me somehow, as i felt it could be manipulated in various ways to show emotion through eye shapes as shown with the front and back examples below.
The front and back views would be used in dialogue shots ideally, as i use them to create perspective in the flash movie.

Further to these i considered motions that would be used in a walk or movement. However this just included the arms as i feel the whole body does not necessarily have to appear on the stage!
I then developed these further by putting them within the flash environment and drawing them there.
