Privacy could be obtained with a screen, placement of potted plants, an open bookcase, but I like your idea for a curved track with a curtain as one option for visual privacy. I would rotate the dining table 90 degrees and move it towards the balcony. I would remove those two chairs/tables because the layout of a single chair that far apart from another chair does not work. You may need to move the seating away from the main entrance because it looks like you walk in and you're on top of a loveseat. In such a tight space with so many doors that open in to the main living/dining - my advice is to keep it simple. Scale the furniture properly and have pieces that are multi-functional. Example- an ottoman that can serve as seating. A bench at the dining table to seat 3 on each side. I would also place two smaller loveseats facing each other in front of the fireplace. This will give you an "entry area" (along the back side of the kitchen wall) and help to define the living from dining rooms. Even if you don't have a formal entry, try to create a bit of space to welcome people.

like so (sorry took liberty with your pic using paintbrush app). in second tv be installed on an island of a solid wall, remaining wall be of glass: use frosted tempered glass for doors n all.. this way you get another expanse of wall to do loads with n utilize full potential (area) of room.. also providing a wall surface on the back of the tv 'island' wall to the sitting area for say a painting, maybe? plus tehre won't be glare on the tv screen either if it's on teh wall-glass partition.. only issue being the slightly longer approach (i-e through dressing room) to bathroom area, which ain't so bad either.. in ur original plan i don't like how a door is sprouting out in the middle of a great expanse of wall... what a waste..

Check the layout . It is made to the scale so that every necessary requirements can be incorporated as per the dimensions .The only structural change mentioned here is the balcony door , which is shifted on the corner and rest of the wall is changed into a big window for the natural light which helps in additional sitting and if you want to develop some greens in the balcony the view from your living room will be just perfect. In the kitchen area there's a breakfast table with hanging display to bar the direct visibility from drawing hall . All the measurements are given to the scale.

Include the ots part and creat a extra room on the side of sofa placement. Make a partition wall for the room with glass or wood sliding. In houzz itself you can find many photos for the partition walls. include the sit out part in the living/dinging space. place the stoor room under stair case. And if you can, plan for more wall to wall windows for the kitchens. Sunlights help kitchen enoromously.
