I think you can start by de cluttering. There's too much going on. If you want to keep the bedspread, I would pull some colors from that. :) Teals, browns, whites. It would make a pretty room.

Hello Shailesh, Glass Fibre Reinforced Polyester may be used for this. It has to be customized for you and is not available in ready made sheets.Where do you stay? Please note that this one is done by Zaha Hadid. With some 500+ international projects under her belt, she is considered as one of the finest architects. Thanks, Nitin CORNERSTONE DESIGNS Bangalore

If you have a small living room go for white/ cream/ beige curtains to make it light and bright. If you have a large living room go for a darker shade like a mocha grey/ brown for curtains to make it warm and cozy.

Its just really messy right now. Too many colours and clashing prints. Is that Puja unit lime green? Or does it just appear that way because of lighting? Either way, it stands out like one more distraction. Pick one base colour add and add prints that go with that base. That TV unit HAS to go. So do that black metal coffee table and the carpet. I would suggest you go with a simple geometric print in the carpet. But apart from these obvious design gaffes, the structure has distinct possibilities, if you do a classic English style. The railing above adds some interest
