Any photos you can share?

Cool shades - greys, blues - would offset the dark, warm tones nicely, but you might use any light to midtone colours you like as accent here. May I suggest you paint the walls in an accent shade, so that your bed stands out more? It is also nice when the accent rug allows you walk in bare feet around the bed, which would mean a minimum 2' border beyond the bedframe sides, ( much more than that, and you will hit the wall, anyway), and a generous amount showing at the end of the bed.

Prathi the dining table and the space is not wide enough. Dining table should be min 1m wide and you need another 3 feet either side for chairs and movement. Get rid of the proposed short wall and partition. You are demanding too much from the space.

Many people these days opt for puja room in guest bedrooms, due to limitation of other spaces. Since living room while entertaining guests there is alcohol consumption, non veg food, dancing, so it could be more disgraceful than a guest room. So, I guess that's fine. I am suggesting the bed on the west wall (the headrest on West Wall) so that you are facing the east (that's Vastu compliant). The bed goes where the wardrobe currrently is. The temple on the North wall with the Gods facing South or West wall with Gods facing east. Rest you could add a bench under the window for seating while enjoying the sunlight and a console on the South wall.
