Excellent work, Im a big fan of Dual chromatic images in technical drawing. I love the atmosphere in this work, its dark gritty and full of techniques that keep me looking at this drawing... I usually use a 0.05 and a 00.5 pen when doing pieces like this! just wanted to tell you, this kicks ass and is worthy of more hits. I hope more people see your work, from one artist to another, keep kicking ass!!!
