Noisy Drain

I took this shot the other day in a storm drain, there was basically 0 light in the drain var the sunlight from the entrance (around 15m away)
Got a very very dark photo with a 30s exposure, but then i decided to up the exposure, I got a very artificial effct, but does it add to the photo?
this shot shows the actual colors (pardon the OOF, was pitch black and used F1.4) http://static.flickr.com/64/181500733_8f5c52677d_o.jpg
