Production of Insert (CD)

The idea behind creating this panel was for the pupil of the eye to be in the centre of the CD.  

I had to make this accurate, so i drew two straight line through the centre, one vertical and one horizontal, and moved the image to make sure the pupil was in the centre.

Then, to check that this was the centre of the hole of the CD, I measured out the width of the main CD shape, as well as the two inner circles, and made sure that they were all aligned.
