Hmm, the darker side of life. Not too many of these entered.
I like the lighting and the detail in his skin/beard. I might have traded some of the negative space above his head for a bit more of his shoulder/body, but it's nice overall. I even kinda like the spacing in the title, even though that usually bugs me : )
A great idea for the challenge and I applaud your creativity. I think this would have been much better face on though... and what are those things around the models head?
