London-based artist Joseph Gartell has been painstakingly crafting these intricate drawings of animals over the past couple of years. Rendered in pencil and ball-point pen the almost obsessive level of detail is amazing - the Bison image, above, is virtually life size at 2.5m wide and 1.8m tall. Considering that each section is carefully shaded in ball-point, you have to hope Gartell doesn't get Carpal Tunnel! This technique means he manages to capture the sinews, muscles and dynamic movement of each animal he draws, but the results are more stylised than scientific, and owe much to Native American styles.
