inspired shelves (yet unfinished)

I've never really loved this living room shelf.

I loved the idea of it ... but it turned out pretty underwhelming considering the space.

So, when my FIL was in town for a few days during graduation this month, I twisted his arm and had him help me hang new shelves. I took the two brackets from the previous shelf and stole the other two from the girl's room and used Mandi's inspiration to hang these shelves.

The only thing I did differently was use regular screws for the studs and machine screws (plus hex nuts) for the shelves because the holes were a lot smaller in my brackets than the ones she used.

I've been trying to decide where to use this corbel from my in-laws 100+ year old farm house when it struck me -- looks like an "S"! Why not use it as a monogram? It adds some dramatic height that I love.

I'm going with a bit of a green theme to bring in some color as well as a little purple and yellow ... to bring out the fun colors in my vintage curtains. Love this little ceramic bird from the hobby store, compliments of my sis and bro-in-law. (Gotta love gift cards!)

So, here's my dilemma. I love asymmetry, but I think that the shelves need some balance. All along, I have been planning to put something in the space below, but I can't decide what. 

Any ideas? Here are a few things I've considered.

String art.

Vintage arrow or arrow marqee (except they are $$$!)

Or a DIY reclaimed wood arrow?

Or a framed photo? Or...? Any other ideas I'm missing? I need your help filling this space!

Last question: if you look back at the photo of the shelves, is there too much "fluff" going on? (i.e. the feathers on the left, the faux branches on the right, and the spikey plant on the bottom?) Should I use a different texture? If so, what?
