The most important criteria for good art is having something worthwhile and meaningful to say! Of course just what is worthwhile to say is open to some interpretation, but what is certain is that bad art never has anything worthwhile to say.
Related to this is that what is worthwhile and meaningful to say must be said in a form that is aesthetically delightful and complex, but not too complicated. I am working always with the light ! From dead to life! Pure matter to bring to life through specific perceptual effects. For me as an artist, a great challenge. I want to raise not only my work in the center. The surroundings and environment of my beholders should become a part in my artwork. All these details have to give a contribution to the totality of the artwork.
