In this picture i used free hand movement with my pencil in order to get the proportion of my sketch accurate, i used light stroaks in order to asure that i put the lines in the right place . however i then used harder lines to crisp the sketch and make it stand out. I think i captured the weight of the model in my sketch well by using these methods and by using a range of tones in my shading to make the sketch jump out at the viewer.If i could improve something it would be to add more detail on the faces of my model as i left them blank.
