Putting on a Mantel of Autumn

Introducing my new mantel décor.  This is better than the last one.  I’ve learned a few things about grouping and height and clutter.   Still a lot to learn, and then there’s my photography skills.

I’m camera-shy, so it’s a big step for me to show the family portrait.  It’s a few years old.  Now I am the only one who isn’t over 6 feet tall.
Close-up of the right side.  Almost everything is thrifted.  I purchased the wooden box and the little mirror years ago, the gourd yesterday, the candle who knows when.  The little pie plates candleholder and the small tray behind it, the pineapple planter and the pineapple dish are all thrifted recently. 
I buy pineapples for 2 reasons:  First, I love that they were a colonial symbol of hospitality, and b) my oldest, Ian, told me about a TV show that has pineapples in unexpected places and it’s kind of a game to find them.  So now I decorate with them and see if he notices.
And on the left:
Everything here is thrifted but the gourds, the leaf and the mirror.
Would you believe the orange plant pot is plastic (sort of) and the label says “biodegradable”.
Now, I need your opinion on something.  The aluminum tray behind the clock.  Leave it? (See below)  Or take it away? (See first pic of the post).

Comment your opinion.
