Although the colour of your photo is slightly yellowed here so it is hard to distinguish colours, I would pick out a deep colour in the tapestry and paint the walls in that colour. I would then take the lightest colour in the tapestry and use it as the basis for all the fabrics in the room: bedcover, lampshades, armchair and curtains. As it is a bedroom, at night, the room will feel cosy, but in the daytime, as you will have dark walls, you will need to ramp up lights, so add a floor lamp on the opposite side of the room from the bed.I think you need to a) either add more elements to your sidetable such as some books and a bunch of flowers and also move the mirror above the armchair higher and closer to the lamp as it seems to exactly in the wrong position.You could also add a cushion and throw over your armchair
