Based on the woodwork you have got done on the wall behind the bed, the following designs might go well with it. Let me know if you like any of the designs; we can discuss how can they be implemented.

Centre mirror with wallpaper on sides can look good

Hey Pallavi , You can plan something like this on the wooden panel , 2 different type of design each side will look nice with hanging lights on the both side and to contrast with you can plan some texture paint at the back of bed .

Let me know if you have any further queries .

Thanks
