yes the wallpaper works the issue is more that the rest of the palette is too pale and evenly matched so the room lacks depth i d keep the pink wallpaper and build the scheme around four stronger tones main joinery a warm plaster pink slightly deeper and dustier than the wallpaper at the moment the wardrobes are too close to cream they need enough pigment to read as intentional painted furniture timber pale limed oak for the headboard and bedroom door keep it warm and chalky rather than grey washed dark accent deep oxblood or burgundy for the wardrobe handles freestanding dressing table and selected piping the current desk colour is heading in the right direction but it could be browner and less purple balancing neutral oatmeal flax and warm ivory for the curtains wardrobe fabric and bedding avoid bright white which is making the room feel washed out for the details change the wardrobe fabric to a plain flax or fine striped linen the current fabric looks busy behind the glass use softly gathered fabric rather than tight vertical pleats make the wardrobe handles larger and more sculptural ideally bamboo shaped in gloss burgundy lacquer keep the dressing table freestanding but make it feel more substantial and elegant a dark lacquered or stained timber piece would anchor the room replace the small scattered pictures with one larger artwork above the desk and perhaps one smaller piece near the door simplify the chair the green is useful but the red and white striped trim feels slightly juvenile use olive or moss upholstery with plain burgundy piping the rug pattern works but soften it to oatmeal and dusty rose rather than stark cream and brown bring more limed oak into view through the headboard door and perhaps a bedside table use aged brass or warm bronze for lighting so the room does not become too pink reduce the scalloped details to one or two locations only the pelmet vanity edge rug and decorative lighting together currently feel overly themed a stronger palette would be dusty plaster pink soft rose wallpaper flax linen limed oak oxblood lacquer muted olive aged brass for archsynth add retain the existing pink patterned wallpaper and freestanding dressing table deepen the fitted wardrobes to a dusty plaster pink so they contrast subtly with the walls introduce pale limed oak to the headboard and bedroom door deep oxblood lacquer to the wardrobe handles and dressing table and muted olive upholstery as a balancing accent use warm flax linen behind the wardrobe glass softly gathered rather than heavily pleated replace bright whites with warm ivory and oatmeal simplify the artwork and decorative motifs so the room feels sophisticated layered and suitable for an older girl rather than overtly childish use aged brass lighting and richer shadowing to give the room depth change to more earthy plaster colours
