the changing still life

today we were drawing a still life with charcoal but the still life kept changing. items would be removed or new items would be put into the still life. in order to keep the still life looking like the set up i had to constantly be erasing item because they would either be taken away or another item would be added and it would cover or overlap the old item. also i had to draw many new things when ever something was added. and i had to move very quickly because near the end of the drawing time the items started to get added and taken away even faster then before. also a big thing was that u couldn't get too attached to the drawings or be too concerned with how it looked and if there were smudges and things like that.
