emerging artists better practice to start with a simple sheet of paper, and then go do the street.Even the most experienced craftsmen first make a sketch on paper and then transferred him to the pavement.
basic concepts associated with three-dimensional images - this art, the term "perspective", that is the image three-dimensional object in space.In order to understand how to represent something three-dimensional on the plane, you need to have a well-developed spatial thinking.
To get a really spectacular 3D image, you need to c
hoose a point of view, that is the position from which the artist and the viewer is looking at a canvas sheet or asphalt.It is from that point of your image will appear three-dimensional.Then you need to determine the order, where the light falls on your figure, because it will depend on the location of shadows in the image, namely the shadows and give a flat drawing bulk.When creating an image, remember that bulky items are drawn closer to the darker contours, and lighter in the center, if the light on them on your idea falls in front.If the light falling on the subject from the side, then your drawing, respectively, will be lighter on the side where the alleged source of light and dark on the other side.
For a start is better to learn to portray a simple rectangular geometric shapes - cubes and parallelepipeds.To do this, draw three axes and place them on the drawing as it does on the geometry lessons.Gradually improving their skills, go to a rounded and more complex images, and then discard the auxiliary axes.For the first studies also recommend choosing black and white drawings, and only then gradually begin to experiment with color.
If you want your picture on the pavement looked impressive, it is not necessary to do his clear rectangular borders.Background desirable to select such a hue that it was combined with the color of the surface on which you will apply it.
