Did you use the "Passion of the Christ" as a reference? Another very powerful piece. Reminds me of the Shroud of Turin and the history it tells. I love the use of the Old Testament prophecy and the New Testament fulfillment of that prophecy.
As an atheist (albeit one that respects others and their beliefs), this doesn't appeal to me in terms of subject matter. That said, this is brilliantly executed. I can easily see why this is your most faved piece, because pictures of Jesus will always be popular when they're as well done as this. You can almost feel the pain and anguish in this image. Excellent job.
