l'aube aux yeux de serpent

to the serpent of Genesis, though?
In that case, the serpent as the one who seeks out its victim and seduces it knowing full well the consequences of its treachery.
'Serpent-eyed dawn' would be the closest, or maybe 'dawn with serpent eyes'.

If you have to translate a prose text into English, I'm not sure that "dawn with snake eyes" will work for an English-speaking readership. I looked up both "dawn with snake eyes" and "snake-eyed dawn" and found nothing except the odd reference to video games. That may confuse the reader of a novel, whereas the same phrase is more appropriate in a poem. If your short text refers to a morning when she kills or decides to kill someone, then "treacherous dawn" could be a possible choice.
