What's that from? "Something wicked this way comes?" It sounds extremely familiar...
I, too, like the photo and I, too, found it a bit difficult to read, but it made me lean forward and get a better look at the picture itself so it's all good. Very much like the meter you chose, I think it was a perfect pace for the ominous, foreboding intent of the piece... very cool stuff, PdV.
Poets are the unacknowledged legislators of the world.
