We just moved into our new home, and we are not sure what to do with this big wall. The paint color is a medium gray, though in certain sunlight can take on either a greenish or blueish tone. Our house is a rustic modern mix. Furniture is all staying as-is, and we will have surround sound speakers mounted in the wall on either side of the TV (65" for scale). Ceiling goes from 9' at left to approx. 15' at right.

Ideas we have had are a large picture above TV (thinking no because of competition), a wall of mixed mirrors of various sizes, styles, shaped, a big decal of some kind of blowing something (leaves, birds) sweeping from left to right (how the heavy winds blow up here), or a hand painted mural of the Rockies (we live on a mountain in northern Utah). Whatever we do I don't want it to look cheap (fear with the decal) but don't want it to be boring, either. Everything in the house has a mountain-type feel whenever possible, be it with the materials or pictures, etc.

Any thoughts, ideas?? Thank you!!
