Thanks,

About processing: I honestly don't know how to avoid that line aliasing problem, maybe I'm doing something wrong when sharpening the picture? Anyhow, this is only visible in the web-sized version. The second one I might try to process again, there could be more shadow detail but I wanted that narrow strip of light and the sky to be very much in contrast to what's in the shadow.

Regarding the connection of the two pictures, I agree with Doug that there is no "substantial" one. I think there are similarities in composition and elements which can be found in both pictures, other than that, it's up to everyone to find his own connections... or not. ;-)
