Oh hi Jatin Shah, I see you have attached the drawings. I'm not really good at layout and architectural plans, just noticed your dilemma and wanted to tell you how you could attach the plans the others were asking for. I guess they have been busy with other things and didn't have time to come back to your question. I will say that the plans look too small to get a good idea of what is going on. If you can find a way to upload them so we can see them better... Maybe start a new dilemma with the larger plans attached. I hope people who know about these things will respond to your dilemma. Good luck!

I wouls get rid of 1/2 the pillows on the sofa too matchy add an area rug that is bright with some other colors to use for accents you have IMO too much brown so I would do blue drapes in the DR take the cloth off the table and add a blue and orange glass bowl for a centerpiece filled with green apples get some pillows in green and orange and a big piece of art work for the wall above the sofa and maybe a mirror on the DR wall and a fabulous light fixture for the DR an arc lamp behind the sofa in the corner so it comes out far enough into the room to light a coffee table.

Hi Anita. For how many hours roughly are your succulents exposed to sunlight? Perhaps keeping them in the sun but giving them a little more water may help.
