Obviously, this is a failed marriage..

Pencil sketch, colored in Photoshop.

I too was stuck on how to execute the Fail theme, and so I went back to my recent nursery rhyme theme and this just popped into my head.

Peter Peter Pumpkin Eater
Had a wife and couldn’t keep her
He put her in a pumpkin shell
and there he kept her very well.
Sounds like a Failed marriage to me!
