Work-in-Progress: Nativity Sheep

I'm slowly coming up on the end of the Nativity figures.  I like them individually.  I like them together as a group.  But I'm still unsure of the look and feel of the background.  I'm trying many different things.  Sadly, none of them really move me.  That may actually turn into the most difficult part of this project.  These sheep are completely adorable though!
