Is this your piece?
Orchestral Songs
Your link for the SibMus page didn't work, and Lulu is too stupid than I have time to deal with.
EDIT:
I just noticed, because you have two HTTPs in your address.
Since I don't speak the language of any of them except Morning, I can't give any comments about your setting.
In measure 62 of the first song, is the tam-tam supposed to ring? If so put a tie on it or put choke or dampen near it because it's ambiguous right now.
I don't know if I feel comfortable with the lack of rhythmic interest in the melody of Verlassen from 9 to 32. I'm not sure if it works with the text, but musically it's not that interesting considering that so many of the notes are the same.
In m.27, which is spelled incorrectly unless that was in the original text.
Hopefully now that I've gotten the correct link you'll get more comments.
