Frederic-- Wonderful work...
I'm curious about the first picture of the chapel--did you do all your post-processing in Adjust 5? I just bought the discounted plug-in myself, so I'm very interested how other people are incorporating it into their workflow--especially for landscapes such as this one where you might have had to bring back the details in the clouds.
At any rate, that's a beautiful part of the world--my wife and I were in Trier a couple of years back, and I could definitely see myself "photographing" my way up the Mosel valley.
