The painting over the bed is too much the same shape as the headboard. I would possible hang the painting over the dresser or elsewhere in the room. Put some vinyl lettering or a large shape over the headboard. The visual weight of lettering is lighter than a framed print and will add some interest without competing with the headboard. Then I agree with the comment about the lamps. Go with a different lamp shade, try a tuna can shape. Also, you need a few dark colored pillows leaning on the headboard. Pick a patterned fabric, with some greens and add a pop of dark orange or red along with the wall color. You can do this with pillow cases too! Also consider a cover for the Ikea chair that ties it into the style of the pillows. Watch your carpet when you pick the pillow covers so that the pinks ( in the picture that carpet looks like a pinky based beige) in the carpet do not start to look dirty. Blues work well with pink beiges if you like that look.
