Oh, those clouds are wow! I poked into your gallery at the other Iceland photos - it is a beautiful country you have rendered so nicely on film. Several people have told me as much, including my father who used to lay over when flying for the US Air Force in the 60's and 70's.
I was noticing how much mid-tone comes through, given an overcast day, snow on the ground & a commercial building side. Michael's right - a trip through your gallery is really a feast.
