I really like this pic, I thinks that you are pushing the boundaries on the 'yellow' qualification though, I'd expect that you will get quite a few voters saying so and unfortunately your score will suffer for it.
As for the image itself, there does seem to be some soft regions that look like they could have been caused by a little too much NeatImage (or other noise reduction tool).
Lots of potential, well done :)
I don't think it fits the challenge very well, and the shot itself lacks anything really interesting...the textures are kind of cool, but the lines are very straight and bland.
