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.

Pendants seem like a better geometric fit.

I am looking for pendant lighting for over my vanity and a flushmount light to match for the ceiling

Hello there, If you're thinking of glass, go for an ACP in mirror finish. It's easier to install. Put 2-3 shades of mirrored finish and create a geomteric pattern on the ceiling. Put some pendant lights and you're good to go. Second, to cover up the grill use a cladding (ACP/ Wood) for framing the window and put a good netural white toned sheer curtain for diffused lighting. To introduce more illumination, paste a floor to ceiling mirror 3' wide on the wardrobe. It will work as a vanity mirror too. Regards, Aurum Ideas and Spaces Bhubaneswar
