If you can't clean up the painted edge, you could always add a 1x3 piece of wood as molding. You can even carry it up to the ceiling to frame that wallpaper. I don't see that paint color in the wallpaper, or maybe it's a lighter version of the flower centers. Maybe stencil on a design using the darker color, or another color from the wallpaper to help tie it together. Then narrow floating shelves or vertical frames or something in the painted areas it you feel you need it. Maybe turn the bed around so the wallpaper is the headboard.

What soft furnishings do you have. You could pic out one or two colours as an accent colour and use that as your Base for the curtains. I currently have cream hessian walls and have a duck egg blue and chocolate curtains. I'm currently making matching Oxford cushion covers for the settees . If you can't find what your looking for ready made buy the fabric and have bespoke curtains made for you.

either side step cabinets must be altered, a low king side bed with storage would be ideal here. even ur metal cupboard once get into the wooden cabinet the space above the cupboards can be closed like a easy loft till the ceiling. so all the clutter n stuff either in loft or bed storage and some in newly altered cabinets.. then comes overall enhancement, like proper curtains with hooks. and clean interior to enhance like cushion or rugs and most importantly some artworks. corner can be lite with a floor lamp..lot more area to play. thanks shradha shah beescheese design
