There are many ways to draw a crescent moon. But often artists prefer stylized images - in the form of a face, a sickle with decorations, a lemon slice, or something else. There are much fewer realistic images, that is, similar to a real month. But everyone can try.
In fact, the inhabitants of the Earth see a crescent in the sky when the Sun illuminates only one part of the moon. The rest of our planet's satellite is in shadow. So why not repeat this natural phenomenon in the drawing?
For work you will need a sheet of white paper, black and yellow gouache, a hard pencil and 2 squirrel or kolinsky brushes, thick and thin. It is very useful to first look at the photograph of the Moon, because it has seas and craters, which are conveyed by contour lines in the figure.
Form is the main thing
Draw a circle with a pencil. See what lines are on the side of the moon that is closer to the viewer. Paint the circle with yellow gouache. Apply the relief of the Moon with a thin brush. Let the drawing dry. After that, mark with a pencil that part of the moon that is illuminated by the sun. Paint over the rest of the sheet with black gouache. Those parts of the moon that are in the shadow will be noticeable, but not very much, that is, exactly how the Earth's satellite looks in the sky.
In the same way, you can paint a crescent moon with oil paints and any others, if they are opaque. Watercolor will not work in this case, the sky will turn out to be dirty yellow.
There is another interesting way to draw a crescent moon like a real one. To do this, you will need thick yellow paper or cardboard, a brush and black ink. It is better to take paper that does not get very wet - for example, from a children's set of thin colored cardboard. A soft and wide brush is preferable. You can also tint the sheet yourself - for example, with yellow ink, which you can buy at an art supply store. To work, you will need another pen or dull scalpel. You can do with scissors or a knife.
Sketch a circle on a piece of paper. Mark the part to be illuminated by the Sun. Paint the rest of the space with black ink and let the drawing dry. Scratch the horns of the crescent moon so that they look like real ones. Several stars can be scratched. In this technique, you can make a drawing in another way, but for this the sheet must be yellow. Cover it with black ink and let it dry very quickly. Sketch the outlines of the crescent moon, as well as the lines of craters and seas. Scratch through the crescent box so that the black relief lines remain. The contours of the crescent itself should be even. Frequent transverse scratches can be made along the inner contour.
