Which is not surprising... The texture, of course. The colors, of course.
And BTW, anybody can do reflections like Eduardo. Just step in front of the window
But, there's a secret that's not really a secret: San Juan, being a traditional city, has narrow streets. Meaning, reflections occur much more easily than in a modern city. And having also a neoclassical architecture with columns, cornices, friezes and decoration, the reflections are richer in elements. The glass storefronts didn't exist in the XIX century, so the reflections add another dimension and speak of a time difference.
