Stairs in Mexico

I was in Mexico and had to make a pit stop...on my way to the

bathroom I notice some service stairs used by the restaurant staff.

After attending to matters at hand, I went back and took this photo.

I think the most appealing part of the photo is the nice blue tones

and transparent sheets of glass in the window. I would appreciate

your feedback an any advise you might have for me.

As always thanks for looking at gallery,

Cheers,

Peter
