can someone with the correct wording and if emdash's should be used of comma's

It was as if – with eyes shut – the street melted away.

or
It was as if – with eyes shut – the street had melted away

Of your two options (and using your words still), I prefer this one:

It was as if – with eyes shut – the street had melted away
