Thanks, the noise was intentional and looks much better at the actual size, once you resize it down and post it on the internet everything sort of interpolates down and looks a bit harsh. I didn't mind it given the sorta dark overpass look.
one thing I do for image sharing is first make sure the image is being saved as a PNG file instead of JPEG and then host it at imgur which offers uncompressed/lossless quality photo hosting/sharing.
