Ego
In this image, Seanna's drawing of herself shows herself as something of a prisoner to her own ego. The series of vertical bars on her head suggests she is a prisoner to her own consciousness; similarly, the horizontal lines on her shirt suggest the uniform of a jailed convict. Her downturned face and the sweat dripping from her brow all suggest the student as a pitiable mess.
And this is exactly as Seanna shows herself: dirty, grungy, surrounded by trash as flies buzz around her. She feels helpless and clueless.
