Nicely done.
Two thoughts if I may....
In all but one case, the images fit the words of the (nice) song, but it would be nice if you were able to come up with more lamplighter images and be able to change the view slightly more often. I found the production dragged in some spots with the same image on screen for a "long" time.
Where the words mention the lamplighter would skip lighting a lamp where two lovers sat on a bench, you image show the opposite. Perhaps showing a lamplighter passing by an unlit lamp with the couple in the background would be very effective
