Here's the second drawing in the Lumen Series. If you'd like to see what these look like framed and on a wall, go to this page of my website. It's also the title link.

I achieved these drawings by gridding the photo, which I had taken from a speeding car and manipulated on the computer. I then grid the drawing paper and transpose the original into a tonal composition, as I have found that the smallest difference in placement of any element changes the image unsatisfactorily. This is a painstaking process that takes between two and four seven hour days to complete and is rather like a test of my patience (I'm not known for that!)

Anyway, I hope this one makes it into the $20,000 Adelaide Perry Drawing Prize. Fingers Crossed
