Super magnified line drawings--O'Keefe connection. I chose this piece because it is a contour line drawing of observed image. I too am drawing pine cones as well. I like the use of line to create the organic composition.
cityscape - I love the black line drawing against the richly colored skies. * I think I would add colorful water below to balance it and show the "colorfulness" of nature contrasted by the black and white of the city.
