gunsan,
i'd love to see the original image.
also, i'd love to see the foreground, (the man) as stone and the background as not. that could be quite striking. or even a little more separation in the two, with one sort of bleeding into the other. i know you have that now, but i mean where one is stronger 'stone' and the other not, but the one bleeding into the other.
but, even as is, i do like the brush stroke look here and the overall effect.
If wishes were horses... there'd be a whole lot of horse crap to clean up!
