I also love the linen/white look. Unlike you and ingrid, I love the look of long, flowing, white curtains in a bedroom... but I can see how they would be boring to some. I will be going with a similar look on my bed-- mostly ivory with either linen or pale blue/green accents and layers. I had planned to use bosporus flax fabric to make a duvet but I wasnt thrilled with the look of it on my bed. I threw it over a curtain rod and am currently loving the idea of it for panels. It is pale enough to be like a neutral but adds some interest to the white-linen color scheme. Bosporus Flax would be less flexible .. but there are other colorways in the bosporus toile pattern that should coordinate with lots of colors as accents. Just an idea

nice room..I especially love your dresser! as much as love chandeliers-no I wouldn't get one..what's your ceiling height? i might be wrong but they look 8 feet high(as ours do too)..given you usually need at least a foot of a chain for a chandelier/pendant not to look awkward-i wouldn't put it over a bed where people can for example..umm..sit up very abrupltly..or..jump on a bed when they see a ..umm..lizard?..in short you don't want to remember not to bang up your head every time. seating areas are different; they're used at daytime when we're more alert etc. Frankly if I'm mistaken and ceilings are 9 feet-also wouldn't do it. Art-would do..something no glass..like an oil painting..without a frame..not too heavy.. or wouldn't. looks nice at is i'd do it if I find something I love..I wouldn't look for a piece to have there just to have there, let's put it this way. (you can see I like to be prepared for all sorts of things)) you should see my purse..)) yes to taller lamps..I like yours btw..I have this personal thing against visual lines perfectly aligned though..I think also some more contrast either in color or material will look nice as for the bedding..well it needs to be something you love (do you have any preferences? more casual? more formal? solid? patterned? do you like to change sets and looks , or would you rather have a quilt/coverlet/comforter that's always there for example? you have many options with bedding. think what's more to your taste), plus two more regular pillows(or two bigger ones), plus one longer accent pillow-ideally..that is, if you like to read in bed for example. the best combination to me. that's personal of course. if you mostly sleep there you can keep it the way it's comfortable to you, more dialed down ..but do get plumpier pillows and one(max two if you like the idea) for an accent..and make it fun..cozy, textured...linen? velvet? something you'll enjoy too, to lean on etc.

You ever consider a wall like this behind it. https://www.westelm.com/m/products/stikwood-adhesive-wood-paneling-w815/?cm_cat=Google&sku=7663776&catalogId=71&cm_ite=7663776&gclid=CjwKCAiA5o3vBRBUEiwA9PVzarcOsj7yJikMhZU7YymnPrCspe7yzW-GJ_XIMVRBDBlQA-Iu1JacgxoC_PAQAvD_BwE&cm_ven=PLA&cm_pla=Art + Mirrors > Wallpaper + Paneling

Keep the bed on the wall in the first setup.. never in front of a window.. move the long Chest to the wall between the two door and put the tall one next to the closet (opposite of where the long chest is now.)
