Desk Study - Contact Drawing

Did this study of my desk to practice my contact drawing about a week ago. It was made using 0.05 and 0.3 micron fineliners. I like doing these as a way to improve my accuracy and train my eye to see contours. It's so easy for it to go hideously wrong but I love the feeling when you get it right. There's always a lot of life to it because your constantly having to observe and adjust where your throwing your line. That and you don't have much room for error, I did make a few corrections using tip-ex so I could continue drawing the rest accurately but for the most part this was done spontaneously.
