Characters for Client

As my job is creating the 3D characters for this project, i thought i would start it up. As Natasha had already visualised her characters in a certain way, I got her to doodle them down so I could work from them. And here are the results:
These aren't all the characters though. The list of characters include:

1. The Radiographer
2. The Receptionist
3. The Child
4. The Child's Parent
5. Waiting Child
6. Waiting Parent
