You guys are amazing; thank you for all the wonderful comments! This truly is my best and favorite shot and I am so proud of it. I am fixing up the original one (it's a huge size; something to the tune of 24 inches tall) so I can get this printed out and put in a frame. Aside from the photos I took in Brazil in March, I rarely print out my pictures because I don't feel they're ever any good. This one though - is my pride and joy. I wish I knew the guy's name or how to find him - I'd positively give him a framed print of it. But I think he was a drifter. He didn't really say anything to me except 'yes' and 'you're welcome'. My mom commented on his beard and asked how long it took to grow but I didn't hear the answer.
I think, not knowing anything about him makes this portrait all the more interesting - there's so many possibilities as to who he is and what makes him the way he is. I've titled the picture on deviantart as "Story Unknown" which I think is very fitting.
Again, thank you for the wonderful comments.
