I've always had a difficult time capturing sunsets, especially at proper exposure. May I ask what techniques you used to do this, aside from the EXIF data on the right? My shots always seem way underexposed, but if I try 0 or + EV, it's overexposed in the sky.
This is beyond awesome, btw. I looked and went "OOOOOO!!" when I saw the thumbnail
Shoot in RAW, and underexpose it so you get the details of the sky. The shadows seem (to me) to be easier to pull out with RAW, when you push the fill light up. Then again, most of the time, you just need to make do with underexposed foreground. I got really lucky here cause the sun was at a level where it was showing awesome yellow light, but also casting it onto the fields in front. The closer ground is still underexposed though as you can see.
