Autumn. Most of the paintings are about 1 square metre in size. The depictions of the human body become realistic rather than expressionistic. The subjects attempt to explore all areas of human existence outside of time and place. The compositions remain well thought out and geometrically structured. The shapes are clearly defined, the colour contrasts are stronger and easier to see from a distance. The works all exhibit a fairly related style.

Summer. The pictures become larger, the depictions are more expressionistic than realistic. The themes remain in the realm of social and environmental issues. The compositions remain well thought out and geometrically structured. The colours and contrasts are calm to unobtrusive and invite close observation.

Summer is divided into the three phases of June, July and August, in which these specific elements appear in ascending expression.

Spring. The pictures are mostly small, the depictions range from realistic or symbolic to slightly expressionistic. The themes are wide-ranging, especially in the social and ecological fields. The compositions are very elaborate and based on a geometric structure. There are many variations in the design of the figures, the strength of the colours and the contrasts.

Spring is divided into the three phases of March, April and May, in which these specific elements appear in ascending expression.
