Digital drawing...in progress

Digital drawing in progress - no quicker than drawing with pencil on paper as the digital paper is the same size and the method of drawing is identical - so I'm expecting it to take 400+ hours to finish. I decided that doing a 2 x layered drawing for my first digital drawing wasn't a good idea as it would take twice as long before I could print it out. Therefore I've started a new single drawing (I will do double layer if this works out). I am quite patient but 800+ hours of drawing before seeing it printed was too long even for me! Size of above: 1016 x 1372 mm, software: Corel Painter 11 (I think I have tested every natural media software out there and this was by far the best for my needs - Photoshop didn't even come close to recreating the 'feel' of drawing and Alias Sketchbook Pro wouldn't allow a digital canvas the size I wanted...) , single layer, 4H, 2H, 2B and 4B default Corel pencils and eraser. Aiming to have it finished by December 2010 and hoping to show a digital drawing at Derby Museum Show in 2011.....
