They are all too long and wordy, and the German parts are meaningless to me because I don't speak German; if I did, I still wouldn't care about any significance they had. Unless you are revealing state secrets or doing a character assassination on someone you know in real life, or an established author writing something totally different from your usual work, I don't see any reason to have a pen name at all. Gone are the days wen published authors could reasonably expect their "secret identities" to remain secret. They've been gone for quite some time too; just ask "Anonymous" who wrote the political book "Primary Colors."
Before you criticize a man, walk a mile in his shoes. That way, when you criticize him, you're a mile away and you have his shoes!
