Please notice the sensitivity of his pieces. The initial abstract artists (e.g.Kandinsky) were saying volumes with their art...and later like everything else in life that works in cycles, abstract art deteriorated to mad splashes of decorative wallpaper meaningless kitsch...it was easy and sellable.
And now? As a reaction, people are enamoured with photographic realism or poster/cartoon art. They have not realized yet that art is an intuitive, sensitive process of unveiling emotions and deep unconscious thoughts that only that individual artist has access to...not Star Trek or Wonder Woman technically correct with a little spoof on religion added to it...
