Those croissants look good. Looks like a similar method to how the Mrs makes pastry for sausage rolls. She puts it in the freezer for about 30 minutes between rolling.
Brötchen looks like the equivalent of our Morning Rolls or a crusty roll except our are not sourdough.
I have been doing sourdough bread about once a week. I have found keeping a small amount in the fridge and then giving it about 3 feeds before using it works well. Mixture of rye, and other flour depending on what we fancy. Have also added olives for a, surprisingly, an olive bread!
