Just one more tonight and the suggestion of doing a black and white version came from my son (you know, the one who is usually the first to add a comment). I’m not sure whether being an architect or a rabid comic book designer and historian is the reason he chose b&w, but it was really fun to do.
I had done one earlier just using blues and will probably add other monochrome versions as time goes on.
I hope you are enjoying this challenge as much as I am!
