Out of the first lot, I think the color shot gets my vote by only the hair of my chinny-chin-chin. I think it's the building with the owl eyes on it the attract me (right side midway with all the bright light at the bottom of it). The B&W's just don't have quite that same punch for me. Of the B&W's though, I give the nod to the first.
With the second lot, I really like the first one. Of course, it could just be a guy thing. =)
