Imagine a painting, strong and powerful, technique showing an experienced, steady hand, needing nothing but a pair of eyes to enter one's sensitive soul. Are you satisfied with what you see? I wouldn't count on that, but I would be quite sure that after a while your head fills with numerous questions.
