Character Development

The Bully:
I experimented with angry faces and poses but found it hard to make them look childish and basically not weird. 

I thought of having the bullies portrayed at monsters and shadows rather than human children. This will add a great visual effect and make the bullying seem more scary to the viewer.

Main girl (bullied character):

I thought I had sorted this character out quite quickly but I felt like she needed more work. She also looked too much like a character already made by Tim Burton. 

I experimented further with the character face shape.

Excuse her lack of hair. I wanted to see what hair style would suit her...

I played around with hairstyles. Influenced by typical children's hairstyles.
