COMPOSITION:
Since there is no 'real' subject in the photo, it's hard to judge the composition. I think you did a great job on the angle of the fence. I would have cropped the bottom a bit to lose the top of the building showing on the bottom right. :)
TECHNICAL:
I think a bit more DOF would have helped the photo. It would make the fence a bit sharper against that brillian sky (not sure if you can control that on your camera or not) Exposure is perfect. Really need that fence in focus though :|
ARTISTIC:
The sky really makes the shot. I hope you tried different angles on the fence and even get more of the fence in. It makes a nice pattern. As for meeting the challenge...sure, there are tons of squares :)
OVERALL:
A solid shot of a solid sky and a fence. Nicely done :)
Composition: Slightly lacking interest. Something silouetted in the pic would be nice I think.
Technical: Focus is off a bit of the left side, which due to the size is a little obvious
Meets challenge: Yes
Overall impression: Excellent idea and good photography. An extra subject would make it for me. 6
A wonderful sky, and I like the repeating pattern of the fence. The fence seems a touch out of focus though, I think sharper would be really cool, and you probably should have cropped the building out of the bottom.
Great colors. Beatiful sky. Although the fence doesn't add as much as it could. I think I'd prefer to see the rust on the fence, or at least some more detail. Perhaps a flash with slow sync could pull out the detail in the fence.
