תרגום - פורטוגזית-גרמנית - Adoro-te muito. Bom trabalho

You simply can't say "Ich liebe dich sehr viel" in German. It would just be "Ich liebe dich sehr" or if you want to emphasize it "Ich liebe dich so sehr" (=I love you so much).

What's more, it's die Arbeit, so it should be "Gute Arbeit!".

Oh, I wanted Ich liebe dich so sehr, somehow I anglicised it, sorry. This is why I should do more translations into German, I´m not used it...

The "dich" stands at the wrong position. It should be "Ich liebe dich so sehr. Gute Arbeit!"
