I'd have to go with the second one because according to the challenge, your suuposed to make an iconic image. Something that people would remember in years to come.

And as cool as the first image is, I just think that it would make a kick ass scene, but not so much an iconic image.

I really like the second one because it looks as though your trying to figure yourself out and your life is a puzzle, and his life is missing some pieces; which I think would stand out more for me, but that's just my opinion. But yeah I def like the second one better.

Best of luck to you and i'll keep my eye on your entry.
