I like the concept, and well executed. The way ahead looks a little uninteresting, from what I can see, but the colour of the reflection and the way it emphasises the sky works very well.

For me this poses and interesting question about focus. I see the bridge of the glasses is in focus as is the sky. Maybe just my small brain trying to get around this, but shouldn't the distance TO the sky be a focal distance rather than the distance to the surface of the glasses? Or did I put my brain in backwards today?
