Line Quality Drawing

This is my line quality drawing. My teacher set up a still life and had a source of light set up. For this drawing we focused on composition again but this time we added line quality in the mix. There is two different ways to show distance with lines one being the thick/thinness and light/dark. A great example of this in my drawing is the bottle in the back. I used thicker lines in order to make it seem further back. But at the same time I used lighter lines to make them seem closer.
