The vignetting is bad in the upper corners :(

Apart from the vignetting which you are correct about, I really like this. Colors are excellent! And I love the depth the scene has and it looks like you nailed the focus on what we should be looking at. Since you have a fairly even blue sky the vignetting is something I would fix in post on a scene like this. It would be harder with clouds or trees and something filling those corners but with the even blue I would just clone it out.
Are you using any filters or lens hoods? It doesn't look like mechanical vignetting to me. Seems to be more optical/natural being so soft. It's strange to me that you are getting vignetting at 95mm on a 140mm lens, you usually see it more at a wider focal length. It could just be the way a bright sun hits the lens.
I wasn't using any filters and removed the lens hood because I could see it in the viewfinder but that didn't help. I also tried removing it in photoshop but couldn't seem to get rid if it using the spot healing tool. I'm not great with photoshop so that may be why. The photo op was really just a fluke. I pulled off to the side of the road waiting for some friends to catch up and noticed the view so I stuck the camera out of the window while I sat there :)
Nikon has a tool that corrects it. I think I can still see it a bit though.
