Really nice pictures, I live in Rheinland Pfalz and go to the woods almost every day where I live but have never seen any snakes here. I have come across a blindschleiche (Anguis fragilis) / legless lizard two times in my 10 years here though which was really impressive. The first one I saw was a very big adult, unfortunately the pictures I had got lost on an old hard drive. - I see a lot of the lizards you posted in my backyard in the summertime here as well.
I was wondering though, do you know any good places in Germany to order frozen mice from? I have seen frostfutter.de but wondering if there are any other places to look in to? There are only a couple small pet stores in my area and they seem to be really expensive for frozen mice and half the time have to order what I need.
