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.

Ah, okay. It is a bed then. It can be converted into terrific seating with cushions, maybe a long bolster against the wall. I like Studio10001's suggestions. Going back to Chookchook's comment up top, I suggest that the first thing you do is find sheets or fabric your daughter would like for her bed and when the two of you have decided on that, post a picture of the fabric here and we can all pitch in with further colour (and other) suggestions. I'm intrigued by what's hanging on the lines strung across the room. ?

The house is a lovely double-wide manufactured home with a gorgeous view of the golf course, a pond and excellent tropical vegetation close to the lanai. I want a relaxed look so I might try linen shades rather than your other ideas.

You're Welcome Mr. Patel :) Yes there are some plants that are better suited to indoor environment here's a guide for the same: but no plant can survive indoors indefinitely. you will need to to keep rotating them weekly or every 2 weeks. are you partial towards glass then sure it can be used. maybe paneled glass partition or a stained one like you mentioned earlier like these: The room does seem a little cluttered, which maybe because of the many different styles and no of things too. I think that can be helped by lightening the space a little and maybe bringing in a bit similarity specially the side tables and coffee tables . i have suggested the sofa upholstery color in the previous comment. shades of sage in velvet. if not then light beige in linen is also a good option. Something like in this picture https://www.houzz.in/photos/architectural-digest-india-march-april-2016-farm-house-in-delhi-phvw-vp~70030021 https://www.houzz.in/photos/vila-by-the-sea-phvw-vp~55949655 https://www.houzz.in/photos/aptes-bona-fide-expressions-phvw-vp~112062304 https://www.houzz.in/photos/sex-and-the-city-phvw-vp~94528292 https://www.houzz.in/photos/brentwood-transitional-home-phvw-vp~99412992 some bright colored cushions and an accent piece of sofa or some bright table cloth might also be good. as for curtains that will depend on the sofa upholstery you use. If you keep the same upholstery i think a nice pastel color would look better. something light. you should also choose light cushions and carpet for these sofas. and if you keep the same sofas i think you should atleast change some of the tables. I would also suggest bringing in a little more light to the room if possible. I hope this helped you. :) Best of Luck, Purva Saksena
