Amos - does this hit close to your imagery idea (esp. the last line)?

The devil called his minions to him, deep in the bowels of hell.
and said, "I've got me an idea, I think will suit us well
Why should we wait 'til after death to torture the souls of earth?"
And a wicked smile wrapped itself around his face's girth.

I was trying to project the image of an evil smirk kinda slowly creeping across this fat, ugly face. Did it work? Is that the kind of imagery you had in mind?
