Since you have a focus light in that corner already, why don't you go for a big brass statue (goddess) or small brass statues on shelves or even indoor plants on shelves or brass bells on both sides with just statue in the center. Statue like the one below will give an aesthetic look. Wish you good luck.

Hi Neharika, if that wall is not exposed to water from outside, you could put a wallpaper there, there are beautiful wall boards also available in the market. Textured paint is another option. We could have the same wall paper/board/textured paint on the piller as well. You might have to move idol of Ganesha and picture near the pillar to some other place. Large paintings look better in living area as half of the wall is covered by sofas. In dining area, even if you cover upper half by painting, lower half remains exposed. So full wall needs to be decorated. More queries are welcome :-)

Since there is already some effort in making this space, try adding minimal additions to this space. The wall behind the painting can have a wallpaper with traditional pattern or motifs. It could be very lovely. Adding a large plant at the corner with a ceramic planter. Try full height curtains to cover up the wall surface and make the window look larger. Hope it helps!
