I think it is important to make a distinction between abstract art and non-representational art. It is impossible to explain what constitutes my art if these terms are not understood.
Abstract art is still linked to the reality around us, viewed by the artist, but reduced to the basic elements (shapes, sizes, color) of that observation. As if the basic elements were distilled.
Non-representational art does not reflect the external world we can see, touch, hear, feel, but tries to visualize the inner-personal world of the artist. It tries to translate the tensions, feelings, intuitions and thoughts inside the artist. It is a different real world, one that is the internal world of the artist. As such, it uses also shapes, sizes, colors but they do not represent anything of the external, tactile world.
