At school, in the classroom of fine art, my son was given homework.
The task was to draw a point still life. It should consist of dots of a single color, or small strokes of paint. You can use only two colors and its shades, it is red and green.
Here is a still life from my son. On the tablecloth are apples, pear, grapes and watermelon.
This is a rather painstaking job. Each individual point should be harmonious neighboring point and eventually turn into a recognizable image.
My son is 12 years old and has no experience with watercolor, but this work tells me that experience is not all. You need to feel this work and have a great desire to do it well. This is a top priority. Experience will come with time.
