i wish the straight line at the top of the image were removed.

Good perspective and repetitive curves fit the theme nicely. Pleasing tones and textures. Although this is a pleasing composition, it's not a particularly powerful image...seems to be missing something, but I don't know what it is...a human touch, maybe?

The top of the left-most arch is a tad too close to the top of the frame for me. I also find the vertical lines at upper right distracting from an otherwise pleasing composition. I don't know that there is much you could have done about them without fundamentally changing the composition (unless you would be inclined to clone them out). I like the tones and lines (except as noted above) of this image.

great curves, wish it were more straight on of a shot.

There are curves, but if you weren't posting this shot for the curves theme would you still find it interesting? For me the answer is no.
