I was reading an eBook from David duChemin today and one of his tips to make an interesting picture is to put an interesting foreground in front of an interesting background. It really matches well with one of the composition techniques from the course I am doing in Cologne. Structure your picture in layers to provide depth.
Cleaning up the archive from 2010 I have found this one that I like and could meet both cases.
P.S: I really recomend the books, ebooks and blog from David. He has a total different focus from what you normally read.
