Remove blinds add a Fabric Roman shade..hung from right under the crown molding...or woven Roman shade..

I think the blinds are so practical in terms of controlling light and privacy. I would find some ready made floor length in a color and pattern that compliments your sofa and add them to the blinds.

What is that in the alcove with the bust just out of curiosity? I think roman shades make the most sense

Hey There: Your window covering doesn't look that bad - it is just not finished. Instead of fully replacing it - what is an option of course - you can frame it in with a decorative panel or curtain on either side. Something sheer and light to soften it up.

Good Luck on your project.
