By using only lines, planes and points, i've created a composition in the theme of sad/depressed.
Black and white is to set the gloomy mood. This shows someone curled up in a jail cell from a top view. The person has spiralled into despair and is a prisoner of his own hopeless world.
This is my interpretation of depression, where our minds are in a state of negativity and we don't know how to break free from it.
