I want those ceiling lights in the pic but can't get these

You don't necessarily need only paintings as artwork. You can put some floating shelves near the dining space with some good crockery like plates or tea sets which can be used for occasions as well. On the wall in the living space you could keep either traditional or modern show pieces.

Hi , I understood what you meant. Seeing the layout you can utilize the wall adjacent to toilet as a position of tv unit and keep your sofa in front at least 7 ft away. your dinning table position should be at the terrace side and considering the size of the room it should be 4 seater. you can utilize the wall opposite to your kitchen for decoration ..book shelf ..etc. If you want a suitable 3d design to be done you can contact me on my mentioned contact details. Regards

have your dining near the kitchen as it's better for accessibility. TV should not be opposite any window to avoid glare. keep the tv in the center and living room around it. Do not divide the space with a divider since these days the trend is to have open floor plan. If you divide then the space will look small.
