Mary Klundt I think that this is an interesting concept as a graphic. I really like the collision of the lines as well as the very simple break down of the picture. It may be a little saucy, but I still think that this is an interesting take on an image.
Short on time? You can still produce photo-realistic art by leaving out large areas the image. The negative space on this piece actually makes it more interesting and as any pencil portrait artist will tell you, hair takes forever!
Intermingle by Satsuki Shibuya. A beautiful, delicate exploration of texture and colour and the mingling of colour. A classic example of Shibuya's minimal use of colour and shape to convey a sense of emotion and personal ideas.
