I gave this a 6. I thought the symmetry was fairly good - although to really nail a shot like this is very difficult in my opinion. The image wasn't 'strong' enough for me, for this type of image, whether that was because of the lighting, contrast, colors, not sure - just needed 'extra' to make it jump off the screen. The vertical framing seemed a bit off, perhaps a little more width, not sure. I liked the concept, but it was perhaps too close to the recent Architecture challenge for me and, as I said, had to have that little 'extra' to really grab my attention after having voted in that.
Well, I've not had any experience shooting architect/abstracts like this but... I personally don't think it has enough interest to catch the viewer. Perhaps it could use some more color, contrast, and a more exciting composition. Excellent try though, it looks like this subject could have some good potential! :)
nice abstract, love the patterns in this one. It might be worth experimenting with different angles/framings, to get the black "line" running differently through the picture. It's good how it is though.
