There is no picture of the bed, but you need lamps as tall as the headboard height.

Your art is gorgeous, so move it to one side above the dresser, and find a lamp that is tall and silver, white or gold.

Place the armoire flat on the wall and top with pretty pottery vases again tall or a full big grass fern that cascades some what over the top.

Replace all hardware to gold or silver or glass for some brightness and sparkle.

Find a chair to go in a corner and have it work with your bedding.....

Choose white or light bedding to add brightness to room and do bedskirt and european pillow shams in a color that works with the chair,

Example of bed skirt and pillow fabric same on bed for a unified look which I think your weighty furniture requires....but a fun modern fabric would add an edge and look good in the room. The fabric will dictate the other colors to be used in the room.....

Small chair, all colors used in curtains are repeated in the room in chair, art, wall color, bed covering, etc. Note chair is white wood trim to add lightness and relate to white in fabric and pictures.....things need to seem to match to add a completeness to the room.

With the beach glass walls, I'd lean to painting the dated furniture for a really beachy feeling. It shouldn't look as heavy as it does. Try a big rug under the bed.

Liking the art.

The rug seems to be two different colors of blue in the two pics. If the shade of blue of the rug is also in the art, it would work as to color -- but not sure of the purpose of having it at the foot of the bed. Placing it in a corner, preferably by a window, with a rocking chair on it, however, could let your bare feet enjoy the rug when they're not propped up on an ottoman.

Alternately, if the ottoman are being used as a window seat, consider using the rug with them rather than at the foot of the bed.

Both your art and larger mirror are tall rather than wide. If you use either over the dresser you could flank it on each side with a lamp.

As someone else suggested, you could put the long mirror over one bedside table and leave the oval one above the other -- or you might consider affixing the long mirror to the back of a bathroom or dressing room or closet door where you might want/need to make one more full view check of your appearance before beginning your day.

Would the dresser and highboy/armoire fit facing each other against the wall? That could give the room a more balanced feel.

Even if the bedside tables/cabinets don't match, your lamps probably should -- preferably tall thin ones with large white shades ... suitable for reading and taking up less space on the top of the bedside table/cabinet, leaving room for eyeglasses, cell phone, etc., too.

If you're considering buying matching bedside tables, you might consider a pair of wood filing cabinets with a finish that compliment your existing furniture. There's a lot of different styles and prices available, even some that lock.

With this wide dresser, you could use a single large hutch style mirror above it.

I've seen a few of those for sale without the dresser at Habitat for Humanity Restore Stores over the years.

Alternately, you could use a pair of mirrors or a single, wider mirror and a pair of modern shelving units with the same vertical measurements as your mirror.

With at least two doors to this room (interior and exterior), you might want both the door and door frame the same paint color as the walls rather than emphasize the door(s).
