Christmas Decorating

Okay, blog world.  I've made requests on Facebook, Twitter and now on my blog.  I'm not super great at decorating.  If I could hire someone to tell me what to buy and where to put it, I would.  But I am not exactly at that point in my life financially, so I'm propositioning free advice.  :-)

Here's my mantle.  What should I do to make it look better???

And while I'm at it, here's the tree and nativity scene.  Any and all suggestions are welcomed (as long as you say things nicely)!  :-)
