Another experiment, this one was done on a piece of canvass, very hard on my mech pencil. I like the feel and the look it gave to a pencil drawing though. It took about 6 hrs in total, over the period of a week. I started with a straight line which turned into a tower wall, then I thought, what would it look like if the wall was blasted out. Then of course I had to show why the wall got blasted, then yada yada... Enjoy Wayne
