Self Picture

This is my picture of myself, it is drew using charcoal, and it is finished with grid drawing. The background of my picture is basically a wall, so I decided to shaded it smooth black. When I finish the work, it is hard to erase the grid line for me, that took me lots of the time to clear it.

My project have evolved by making the picture more realistic, basically, I tried adding value to my drawing and shadowing, and it does not work well because there is basically no shadow in my picture, I photo it with dark background and it is lightless. So furthermore, I have tried to add the shadow to fill the blank space, to draw it realistically, every line needs to belong to a shadow, but I made mistake in here, I drew the background and set the shadow into same color, and it doesn't shown.

This drawing related to my life as, I am clearly drawing myself from a picture, 1*1 size. If I could make my art stronger I will put more time into adding value and shading darker.
