I've been working on this drawing for three days, it started as you know as a drawing, then I added watercolour, then thought about how I'd like to proceed and settled on colour pencil. There is a nod to Nevinson's Acetylene Welder print, (which blew me away at an exhibition of war-time art in Sheffield last year).
Here's a link with info to the Nevinson artwork: http://www.vam.ac.uk/
The image is 48x30cm, and has pencil, watercolour, and Derwent Colour Pencil. Next week I'm hoping to make an intaglio print version for the York Open Studios in April.
