Default Too much noise/ grain: compression issues?

It seemed okay to me before I saved the shot from Lightroom, so I'm thinking that is where the issue is.

Any suggestions?

I had my ISO set at 100, gave it a little contrast boost as it looked a little washed out. Also I decided to level the shot according to the building at right wiht the chimney, as a lot of those poles probably do lean. But it didn't seem to be an an issue with the screeners.

There's noise all over the train and in the sky, unfortunately. As Charles mentioned, it's also leaning noticeably to the right (the poles may lean, but the building/chimney and the train don't).

Though there is some noise, the issue to me is not blatantly obvious.

In regards to the impression that ISO 100 implies safety with regards to noise, I'd suggest three solutions:

1) Be wary of the sliders in LR - the more heavily you use them, the more noise you will incur.

2) Be wary of 3rd party filters (like NIK). They tend to introduce noise rather quickly.

3) Be careful not to underexpose - boosting dark areas will introduce a lot more noise then reducing bright areas (Google "Expose to the right"). This is the case with most cameras though more with Canon than Nikon.

PS - You might try some noise reduction followed by sharpening, just do not go overboard!

The noise within the urine colored area in the sky is very noticeable to me

Odd - noise is very apparent now. Easy to fix, though. Daytime eyes, maybe.
