What color shutters are you getting? If white, I might choose white matchstick blinds for the window above the window seat.
Your room has a lot of pretty neutrals, textures, and designs. I do not see any art on the walls. I suggest something other than another neutral for the art. I would select a color from the art for the fabric for the window seat cushion.

Thanks! No art yet as this room was just done over so still decorating. Don't love the privacy "stickers", was thinking maybe a thin linen panel ? Plantation shutters will be white.
Figured I'd add color at the window seat cushion and tons of dec pillows, just can't figure out patterns that will all go together

Pretty room! I thought the same about the privacy stickers for the door. You don't have much space for window panels and I think the film will show off those pretty doors. Maybe keep them in mind, when installed correctly they don't look cheap at all. I love the idea of a roman shade above the window seat and I love plantation shutters. The only thing I might suggest are drapery panels along the window behind the sectional. That window looks small for that bug wall and panels would help give the illusion of a wider window. Gold luck!

*big .... Not bug

Also, I would start with an area rug that you like and then you it will be easier to pick out fabrics for window treatments to coordinate.

Beautiful room ! Looks like roman shades is the way to go for that window. I think there are a number of options for fabric . I would aim for a stripe pattern. In the greys /white ...perhaps a darker shade of grey...to compliment what appears to be grey tones in your furniture.

Alternatively a bamboo roman shade - for a more neutral look.

Just some ideas ...
