@SandyRiver24 German is only harsh if you haven't mastered it properly :-) Typically Anglophone comment to make... Even Renee Fleming's German is still appalling after all these years. Good luck!
@reecty01 The vibrato is not the (major) problem here - weird diction and absolute stasis in the music. "More" is in this case not "more", but far, far less.
Major intonation issues 1:22 to 1:26. Thank god for the orchestra!
