If you love that wallpaper, use it in bathroom. Not really right for behind bed. I would go a drum style chandelier. In a silk pale gold. Your bed looks zen or Asian to me. I love it. But, you don't. Need to much with it. Keep it simple a more formal drape on windows, color would depend on wall color and bedding. I'm thinking a dramatic peacock satin. Use a lighter same tone on walls a rich teal. Ceiling can be gold leaf. With alight that cast shadows on ceiling at night. Then your wall paper will tie in. Furn should be mirrored.

To hide a window above your bed and make it soundproof, use soundproof curtains or heavy blackout drapes to block noise and light. Install a removable window plug made with acoustic foam and mass-loaded vinyl for effective noise reduction. Alternatively, consider placing acoustic panels or a built-in bookshelf over the window. You can also extend your headboard or use frosted films and blinds for an aesthetic, soundproofing solution that blends seamlessly.

I really liked the indirect lighting and the bar light fixture.

Yep, I agree it's nowhere near Scandinavian. Although I tried hard to emulate it with the resources I had and conflicts with other family members, but oh well. But I'm trying to emulate the Scandinavian theme at least in the paint job. Do you think if I somehow achieved it at least in paint job it won't look good? I really like the color scheme of Scandinavian design. Edit: I really like the minimalism and coziness scandinavian design provies. Although, I do have to mention that I didn't mean to say that the photos that I've posted are necessarily scandinavian. I was just talking about the colors especially the white color.
