Charcoal and eraser

Using charcoal and an eraser I firstly had to cover two A2 pieces of paper with the charcoal, and then began to define the bone that I was using into it, using the charcoal I etched the initial shape to help create a basic idea of where I should begin to draw. I then started to use the eraser to help me draw and define areas of the bone which helped give a better definition of the texture and tone.

The next week, I then added a new element to the drawing which was a rib cage, on the left you can see I began with defining the bone and using the eraser to create the texture and tone within the surface of the bone itself. When I took a step back and looked at the drawing the bones didn't really stand out, so I then proceeded with the charcoal to darken the background which made the rib cage appear to pop out of the page and created a sense of  an area as to where the bones may be.
