Let me first off by saying that this is a great piece of art, it gives me the illusion of being behind him as he walks through this terrain, and the darkness gives me a sense that he is going to struggle. I love the blue mist coming from the deaths of the cave bellow, it gives the guy the feeling of actually being alone when he embarks on this journey through the cave. So overall I rate have to rate vision a five ( it looks spectacular). I seen a few pieces of art relating to this type of subject, but this is great I rate Originality a 4.5. I can't find really anything wrong with the technique, I rate a 5. For Impact I would have to rate this a five, even with out the guy this piece of art would be outstanding.
