Window Framing, Thomson Style

Every time I look at an Alexander Thomson building I seem to see something new. These heads forming columns in the window frame, on the tower of the St. Vincent Street Church.
The amount of detail high up on the church tower is remarkable.

He's forever being called "Greek" Thomson, but I've always thought there was more of an Egyptianate influence. And looking at the top of the church tower today, I was reminded of Angkor Wat somehow. Weird.
