I found this for you

hi, you can try wood panelling, with mica on normal timber, also great wall papers available nowadays, distress finish on wall paper gives a rustic touch, with roped up bulbs as lighting on the walls ( as hangings) on the corners.. also bricked stony walls look superb!!

If you like to keep the traditional look, bring in curtains, paintings and more lights. Repainting the walls will be a good idea as it can create more freshness. Try a feature wall with red or maroon paint or wallpaper that compliment the flooring. The book shelf can be changed to something wooden. Or If you want a contemporary look, choose wall mounted / floating book shelves.

Vivek, With all due respects to family emotions attached to it , the door looks very heavy. You may want to lighten it with light shades of paint and by hiding few sections of it with HPL or wood. That reverse swastik on one side should better be corrected. Thanks, Nitin Cornerstone Designs, Bangalore.
