Don't worry about sounding like a native at this point. You most probably never will and that's totally okay. A slight foreign accent is actually quite charming. Learning a language is never about total assimilation to the target culture or language. It is about creating your own identity.

By the way: Pronunciation in German is called "Aussprache (f)" which means as much as "speaking things out" and a good phrase to remember is: "Wie ist meine Aussprache?" (=How is my pronunciation?)
