Yea it definitely doesn’t sound as bad as many other Germans but I don’t have the American sound down to the nuances so you could definitely tell. Idk why but I think it’s quite hard to get the nuance if you haven’t been raised with the language, it sucks if you don’t sound 100% authentic, I hope it will come with time.
But you really have to study each tone down to its core including its cultural context to get it perfectly. Imma try to do that though for sure
Lol I’m like the exact opposite, if someone isn’t smiling at me I’m thinking “Did I do something wrong?” but of course I know that not everyone is smiling at you unfortunately
