Havanna Blues indeed, and they act as a great link between the elements in the photo. The blue car is an eye magnet and immediately triggers thoughts of Cuba and the blue wall leads to the old ornate and open architecture, which also echoes Cuba. On the way we discover one then two men, both dressed in blue, which give the image a bit of life, albeit slow-moving life. I like it.
Yes, all the time, and finding something worthwhile is how I imagine a prospector feels when a glint of gold shines amongst the gravel in his pan.
