Translation Quenya phrases

Hi there,

How would change auta i lómë (the night is passing) if you wanted to say the night has passed?

And how would you translate the following to Quenya?

Hail Arien, flame maiden, lady of heavenly fire! I greet you! My heart sings with joy seeing you!

Or:

My heart sings with joy at the sight of you!

Compaired to "Aiya Eärendil Elenion Ancalima!" , i think it would start somthing like that: Aiya Arien, Nárwendë...

Maby fëa would be better then heart...?

Namárië! Elenmir
