Back onto shot one, if we haven't beaten it to death already.

Several things could have made shot one a lot better.  Number one, it isn't underexposed any more than necessary to keep the sky from blowing, it's just about right to be able to get the whole sky back with a bit of highlight sliding, provided it was shot raw to begin with.  In a shot with patches of bright sky, care needs to be taken to keep an eye on the histo and not let any of it blow by much.

The OP did shoot raw, so if he had even taken the minimal step of opening in ViewNX2 and bringing down highlights and raising shadows for a total time investment of about twenty seconds, it would have made all the difference.  Maybe you would do us a favor Edo and try it and repost.  Or better yet, Dropbox the raw and ley us have a crack at it.

I hear the ADL fans, and certainly ADL would have brought things into better balance, but there would be even more noise.   I would also have tried the in camera HDR with a two stop spread.  Now before you guys hoot this down, go out and try it, it works extremely well.  Two separate exposures within a split second, combined by the camera in a few seconds.

Number two, there is no call ever to shoot at 1600 for a scape like this.  You're throwing away detail that is totally needed for this shot.  ISO 400 at f5.6 at 1/60th would have been close to the correct exposure. With VR, you could have gone clear down to ISO 100 and really brought home the bacon.  The best setting for the Tokina lens is f5.6, f8 isn't as sharp.

This is what the D7100's ISO 1600 should look like with a decent raw conversion with CNX2's lousy NR:

You cannot get this quality from an OOC jpg, sorry.  I had hoped for better OOCs, but it didn't happen.  Boo hoo.
