I had to move a lot of vertices around the eyes in order to create the blend shapes. I had to also keep checking that some of the vertexes were not overlapping. I also made sure that it flows around the eyes very well. Poor blend shapes equals a poor animation. Before i did blend shapes i was a bit worried because i did not know what to expect. But i actually enjoyed doing blend shapes.

Reference on blend shapes

I also found it useful to look at examples of blend shapes in order to know what i am dealing with. Looking at this piece of work gave me confidence to do my own blend shapes.
It gave me a rough idea of what i have to do.

Reflection/Blend shapes

For the Owl i have created some blend shapes in order for the owl to have facial expressions. From speaking to Depa i know that the Owl is going to have a mechanical and slow movement with the eyes. So in order to make the animation affective i exaggerated some of the expressions. I made the eyes really wide open. It took me a while to do the blend shapes because i want the animation to be as smooth as possible. This requires a lot of patience. The more blend shapes i do the better the animation. Depa just wanted me to do 4 expressions because most of the movement is around the eyes.
