Giving directions

Hi,

I am practicing giving directions. Are the following sentences natural to a native ear?

[color=blue]Once you enter through the revolving door, go straight, passing by a staircase going down, until you reach a junction, where you will see a passage going to your right, with a glass wall from which the outside is visible.

Thanks,

MG.

Hi,

My suggestion:

Once you HAVE GONE through the revolving door, go straight ON, PAST a DOWN staircase until you reach a junction, where you will see a passage OFF to your right, with a glass wall THROUGH which YOU CAN SEE the outside.

Thanks Alan.
