Place a piece of furniture in front of the window that is the same size or larger as the window opening.

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.

Well I'll try to make a 3d of the room and upload it. But that will take some time. Thank you :)

Hi Zainaba, You may go for both American pleat curtains as well as roman cloth blinds for your window. 1] American Pleat Curtains These look lovely and add elegance and grace but have a tendency to "fly" with air circulation in the room. You can provide a weight chain to solve this issue. Also avoid giving lining to these curtains. Some of them such as linen and cotton curtains tend to shrink after being washed and their polyester/satin lining does not. In the process you may lose the shape of the curtain. Best to stitch the curtain and the black out lining separately and provide a two track curtain.Also keep the curtains length more than that of the window so that its bottom gets tucked in behind the bed back/headboard. It looks neater that way. Also, these can be easily removed and washed at home. 2] Roman Blinds Roman blinds are a neater option as far as window shades are concerned. The look graceful and showcase the fabric, its print and its make way better than the american pleat curtains. However, they are difficult to remove and you need to call the curtain tailor to have them removed for washing. Hope this helps! All the best! Regards, RnD Atelier Nagpur
