Graphite Drawing On A1 Paper

In this lesson we were given an A1 sheet and a 9B graphite stick. We were told to make a view point for a picture of layers that we have taken. We then had to draw the image on to the piece of paper. With this drawing I tried to be expressive with my marking but I feel that they have come out like scribbles on the page so I will improve the drawing by trying to make the expressive marks more sutler by using my rubber to blend the colours covering the expressive marks.
