There is contrast between the traditional furniture and the focal point of the floor which pops, draws attention. I would recover the sofas in cream colored soft fabric - suede. I would leave the curtains grey, and put down a large neutral area rug. The edges of the room would show the pattern of the floor. I would color the wall and add texture to it, but not too dark as the room will appear smaller. Add a picture and put a nice plant holder, large vase in the left corner of the room - an oriental-style vase. Or, a cream-stripe fabric on the sofas. You could go soft or bold in this room - depending on your taste.

thank you for your advice, but the leatherite will only be used on the bed back rest and cupboard. The cupboard panel and all around the cupboard will be polish. As per your input, the bed back rest or the whole bed should be darker color ? the cupboard and the bed should be of the same leatherite color ? which color And the whole room should of which polish ?

Yes, moving the bed under the picture wall would be good, and provide space for a chair and ottoman as you mentioned. And i have actually put a new set to curtains today which is a slight brown colored one. And I was thinking about painting the walls with the picture and the one with cupboards in a dark red shade and the adjacent walls something between off white to cream color. I plan to change the floor tiling too, but not at the moment. I've been thinking of making it a wooden flooring. But not sure what color to use.

I feel partitions are not needed. You already have too much for the space. Adding a partition will shrink the space further. The simplistic solution, you do not wish to discard any furniture would be to paint all the walls in lighter pastles. And use some wall painting frames to highlight certain walls.
