Drawing a bike is not as easy as riding one..

Drawing a bike sounds easy, but don't always be so quick to judge something. During the time I spent on this bike i learned many things about art and the way it works. For example; shading, the shading on the bike was definitely one of the most important parts, it shows the shadows of an object, the texture on a metal, and even the depth of a certain spot on the bike. By adding the shading on the bike (or any drawing really) it helps make it look more realistic, and the more realistic the better the drawing is. Right?
