You can learn to draw well at any age. The main thing is to depict the selected object in stages. Then a picturesque picture, for example, a waterfall, will gradually emerge on a sheet of paper.
You shouldn't go straight to watercolors and gouache, it is better to first master the technique of creating a picture, individual details using a pencil.
Making a drawing scheme
First, a sketch of the waterfall, relief and accompanying landscape items is made. Mark a rock at the top of the sheet. It is from its top that the waterfall will flow down. Designate it schematically. Let it be a rectangle stretched down for now.
Draw a small lake at the foot of the mountain, which was formed by the falling water element. Keep it round or slightly oval. To the right and left of it, mark 2-4 boulders. They will lie at the foot of the mountain.
We add volume to the picture
The drawing should take on more voluminous forms. In place of the rectangle that represents the waterfall, draw some vertical lines. Subsequently, these will be streams of water.
Make the right side and then the left side of the rock more realistic. Add volume to them. If the rock consists only of stones, then rounded boulders are drawn. Maybe your rock is full of vegetation. Then you can still schematically draw grass, small bushes, trees on it.
Next, you need to shade some parts of the drawing with a pencil. The strokes will help to make the picture three-dimensional. If they are applied to the edges of the boulders, it will be noticeable how realistic these large stones become - they acquire a convex shape, chiaroscuro appears.
Determine which side of the picture the sun will be in order to mark the shadows and light in the drawing with a pencil.
Vertical strokes will transform a sketched waterfall into a dynamic, flowing one. In the place where it flows into the lake, draw some wavy lines. Then it will be noticeable how the waterfall hits the surface of the water.
Small details - stones, grass, it is better to hatch with short lines. And the large ones are a waterfall, the lake is long.
Draw the accompanying landscape
If in the upper part of the picture you schematically depicted bushes, trees, now it's time to give them more realism. Let the fir trees rise in the upper background.
It is quite simple to depict them. The trunk is drawn first. Further, branches extend from the top to the right and left at an angle of about 50 degrees. A pencil will also help give them fluffiness.
Make very small strokes, first on one and then on the other side of the branch. This creates needles throughout the tree. In the very distant background, trunks with the outlines of branches without needles can be seen.
Draw circles around some boulders that are not on the shore, but in the lake. It will seem that they are walking on water, which is carried from the top of the mountain by a waterfall.
That's how easy it is to draw a waterfall with a pencil. If a child did it for his parents and signed his first painting "wadapat", they will still understand what he meant and hang the painting in a prominent place.
