some lovely sketches by Chris Lewis, a good friend of mine, absolutley no idea why he hasn't been given a job in car design. He's just started a blog, check it out - http://www.calew85.blogspot.co.uk/
I challenged Chris to a sketch off recently, generally to keep our skills up and get a bit of practice. Mercedes Motorbike was the first brief, posts will be up soon - sneak peak
Going to try a sketch a day (try), see how much I improve, I don't have a scanner/wacom or even my pc, so it's old school black polychromo and pictures off my phone.
