i think they made a great choice for the staging and think you should do the same. you'll lose the bottom of the window too, but its good balance in a tough situation.

if your headboard is higher than the midpoint of the window, you might consider compromising on a lower headboard.

move the bed to the left (in the photo), and get a wall treatment that extends past each side of the bed. hang the curtain so it makes the window look larger than it is, and centered over the bed. Then for staging it'll look symmetric, and for the rest of the time, you can open/tie back the curtain and enjoy the natural light.

A grey shantung or similar curtain would probably work well with your décor.

what is a deficit turn into an asset. The staging balances the window-a king size bed will actually work better to negate the bottom of the window, but it needs to be balanced, as accomplished with the staging.
