Observational Drawing: Garden Rock

Drawing of a garden rock the medium used is Charcoal and Charcoal Pencil, after doing some thumbnails I decided to draw the whole of the rock rather than just a section. The rock interested me with all its cracks and white lines going around it. I could do with adding more contrast especially to the darks, it seems like the fixative has greyed the darks down. The piece was done on A2 Cartridge Paper, the image below is a photograph of the drawing.
