I like the composition of your shots. I've been to Acadia several times and I can appreciate your panos but your sensor needs cleaning. When I opened your shots to full screen I saw many dust spots on some of the photos. I just used the Copper Hill kit on my D600 and it makes a world of difference.
Thanks everyone for the comments. Yes the sensor is horrible now, more obvious on pictures I posted in this thread: https://www.nikoncafe.com/vforums/showthread.php?t=345224&page=97. Didn't get to take care of it before the trip. I think I'll send to Nikon first as it appears Nikon is replacing the shutter mechanism in some cases. I will order the Copper Hill kit and do it myself next time.
