I chose this video to post because I thought it was really interesting how you can see the actual cross hatching and line process being completed. Obviously, the main use of line in this piece was cross hatching which was done so carefully and meticulously. With the contrast of dark and light the artist did with the cross hatching, the forms have more depth and look more realistic. The way the lines towards the bottom are drawn diagonally, your eye is directed from the top left and down to the bottom right, across the piece. I'm not entirely sure what this drawing is of but I found it interesting and a good example of line.
