Here is my second attempt.
Loved the grail. But wanted the hands to be holding the stem of the grail. Also..the figures appeared too realistic....too "there." He did like the sense that they were now emanating energy but it appeared too much like fire to him. At this stage he wanted to give up. The process is a bit arduous and frustrating after all. However...he did give me some clear directions.....he was now certain that he wanted the background to be dark blue or black and the emanations to be white and look more like lightening than fire. He also wanted the figures to be less distinctly figures.
Here is my third attempt.
