Fellow German here. From a grammatical standpoint German is a really flexible language while English isn‘t. I only recently found out about it during my Latin studies (selftaught) and comparing Latin to German and English. The problem with expressing a thought in German might be a side effect of the ubiquity of English in so many fields: we are just used to think in English terms that it becomes a second nature.

English has so many idioms that are nearly impossible to translate elegantly. "go to town on somebody", for example; a good part of learning English is not just learning grammar and vocabulary (although those are necessary), but learning all these idioms (which is kind of an open-ended process).
