Hi Mudit,
Some few basic changes, like highlighting the carving details with a white PU paint, changing the upholstery to a softer look and feel fabric will give it a newer look while still maintaining its strength and durability.
You may also think of adding a backdrop pop-up wall colour / traditional painting to accentuate the area.

Hi Thanks for the response. Any sample image to visualise it?

You may look at something like these for references

you can change the uphold,or else you can do polish on it.... because of it you can increase durability of it...
