There's some really nice buildings there and they're the sort of shots you'd see on jigsaws, especially the last one. Are 2 and 4 maybe slightly overexposed?
Beautiful! You've just reminded me of our visit to Alsace, many years ago when our boys were little. It's a great part of France although we found it a bit expensive at the time. Colmar looks very similar to Kaysersberg, that'll be the Germanic influence.
