This is a graphite pencil drawing of some objects arranged in a manner which draws an implied line around the image starting from the stereo, due to the blackness of it, then drawing your eye up the mannequins left arm and down its body then up the black wire back towards the stereo again.
The drawing uses the rule of thirds to position the stereo and the mannequin so that it attracts the viewers eye to rest at the main vocal points and not just glance at them. This further enforces the implied line and allows the viewer to take in the details surrounding the main focal points. like the windowsill which the radio is resting on.
This image is not perfect due to the fact that there is a blank space in the top right of the photo. This imbalances the image slightly due to everything being on the bottom left hand side and doesn't draw the viewers eye around the entire image.
