Dave Morris is right, the plunger and gun are on the wrong sides in the previous blog entry, damn! I was too busy moving elements to gett the symmetry of the beast in the background right. Originally the Dalek eye was pointing the same way as it's torso, I wanted to create a sense of movement and confusion in the Dalek so 'flipped' the head horizontally in Photoshop. These sketches show the original sketchbook idea and the composite I was to trace for the final drawing.
The image flipped back again to get the plunger and gun in the right place.
