Why can't you move anything around? It that a plain Christmas wreath?

So the spacing on the items is a little to spread out. Keep more cohesive, and hang them lower. In my opinion the wreath is not a good addition. Too close in scale to the two square pieces.

Use the 2 white pieces over the bed. Hang them 5" above the headboard and about 3" apart. The wreath adds nothing to the space

The carved squares would look better on a smaller area. The wreath...............there's nothing to say about how sad that appears.

Select larger canvas or art works for the large wall. See GreatBigCanvas.com You'll get 50% off your first order.

You need to layer in some lighting. Are there any windows in the space? You need side tables and lamps, and something larger on the wall.
