Here are some photos that may help you. You have the ceiling height to have a nice heavy rod just above the top of you window that could run the ceiling width. That will give you the space to draw curtains back to expose the entire window. I highly suggest that you work with a designer. A good designer has access to literally thousands of fabric choices and will be able to help you in selecting the perfect fabric and design for your room.

Namrata, If your intention is to let the light in and yet maintain the privacy then vertical blinds would be one of the good functional solutions. See the attached image for your reference. Note in your pic at this angle it looks like the TV unit ledges have been taken to the far end of the window wall. This shall pose issues with your curtains/blinds as well. We mean to say your curtains will not close on the right hand side completely.\ Hope that this is not right. Let us know if it is. Thanks Nitin Cornerstone Designs, Bangalore.

that is what i have added if you can see the pic above.. want some suggestions on partition that i can use between dining and sitting

I would suggest u to go with white sheer and light grey curtains only. If u want want to play with bright colours then it is safest if u add them in form of accessories or decors, reason one being the space is small n it’ll look more crowded then. It’s better if u avoid orange n yellow in this bedroom at least. If u can give a better picture of the accent wall colour here it would be better. Then u could go with a darker shade of it to form the colour scheme. White+Grey+Purplish brown. That’s it.
