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.

Thank you for posting the pic. Is it just open space opposite the chairs and a blank wall with the entry door? Any windows on that wall? Is that a table showing on the right of this pic, or a counter between living room and kitchen? My first thoughts are that those chairs must be pulled away from the wall and angled in some way, and somehow you need to find space for more seating. Could you angle them towards each other against the room divider, or is that a cupboard you need access to? Then you could turn the table 90 degrees, and place other seating facing the chairs. I'm liking the idea of picking up on colour from the green glass on the table, but I'm not sure how yet. I have a busy day ahead but I hope to check in later.

It is often best to choose the wall paint colors last. These photos (click to enlarge) might give an idea for working with the colors your chose in the bedroom. Substitute modern furniture.

Both the laminate and flooring are beautiful, but I don't think they will compliment each other. The flooring looks to be red oak and as it's name indicates has a lot of red in it. The laminate has a rustic feel and could be imitation walnut which is very neutral, wide grained and has no red. I think the lam would be fine with the paint, but not sure about the floor color. Are there other options for laminate wardrobe? Or do you have an option for flooring?
