Your room is big and void of color. Yes there is too much brown. If not replacing. Add light colored pillows big in a cream print. Add teal to mix. Get a 8 x10 area rug. Go cream base and a contemporary design in very bold colors, red, yellow and black, teals mix it up. Can you get regular chairs. Those look like game chairs, can they go in kids room? Pull sectional into room out of corner face TV wall. With big rug and a 36" ottoman square. In a color. Maybe zebra for fun. On TV wall. Get a wall to wall floor to ceiling or close to it wall unit. Ikea has some go white. Get. Long low media cabinet. Also Ikea in white. Place TV on top. Fill wall unit with colorful pots candles books. Just don't over do leave 50% empty. You could paint that wall a darker (2) shade of walls. After you have centered sofa in room more. On wall behind a very large art contemporary 40x40 hang very low. On empty wall in dining area. Get a long 6-7 ft chest. Something different. Asian feel red lacquered would be fun. Over it add big art piece bold colors 40 x40 hang 6" above top of cabinet. More art big by dining table. I would change chairs to a high back leather in Teal. Pier one has them. Your whole place needs color. Area rug under table 8 x10. Solid teal. Add big palms in corner to fill and warm up space. In chairs get two swivel barrel type in a print. Modern go taupe and blue/greens. Wi Dow panels on ends only in teal. Ck bed n bath. TJMax a good source. For art ect.

Thank you Groveraxle for the virtual ! you are too good a designer that is why I cannot help troubling you ;) you have your biggest fan in me ever since your first advice:)) As for an in-house designer I am certainly going to call somebody soon . Just that I get such a lot of options and great advice from highly accomplished and talented Houzz designers ..I would be better prepared after these conversations ..please forgive me for pestering you guys like this:)

Hi Maam/Sir, I would recommend you to share a better perspective pic of your room where the ceiling is also visible because if a room does not have enough of natural lighting then some artificial effect like a false ceiling treatment would really give a great boost to the look and feel of your space. I would also suggest you to follow a concept like i can see there are a lot of varied colorscheme happening in your room so changing a curtain will not be much help. You should find the right patterns maybe like adding some pastels or i can see that some red or maroon color is involved in your room so try to match the lighter version of these elements. Also adding some wall treatments will give a good vibe in this room. - Layden Wangmo [senior design consultant] MAD DESIGN

example: winding staircase, source internet Little modification need to be done for entrance lobby opening, where you could accommodate a shoe rack and the complementary vertical wall can act as a amazing entrance decor wall wall in Kerala style heavy color play or texture/wall cladding with brass mural.. by doing this you get space to mount TV unit and a good space for sofa arrangement (make sure sofas are light as the space is less to accommodate baggy sofas), staircase can be made in the shape shown in sketch plan, with marble finish on the foot steps (or as per interiors), space in the bottom of staircase next to master bedroom wall can be utilized for chest of drawers or a tall furniture, make sure the staircase bottom part to be casted smooth in finish.
