Many thanks for the nice gesture 
The noise is due to long exposure in low light. ISO was only 400 but when taking pics at night in very low light with long exposures, noise creeps in even at ISO100. Moreover, since i shoot RAW so it has more noise and more details by default. I prefer to keep more detail out of RAW as compared to high noise reduction that is why u will see little noise in my night shots.
If u want to upload larger shots then upload them at flickr and share the bbcode here on PW for whatever size u want to upload.
Here is how to do it:
