Simple Lines
Simple lines can create a dramatic image of your concept. Pay attention to your vanishing points and the horizon. Emphasize the big details. Use shade and shadows to add to the 3D quality. Knowing when to stop is the key to a successful sketch.

Cool, man. What’s the name of the building ?
This is an image taken from my sketchbook. It is the first sketch of an image from my thoughts as I contemplate a vision along Queen’s Road East in Hong Kong. One needs only few lines to bring life to concept!
Thanks again Dear. I will keep you updated.
