Try posting under Design Dilemma section for suggestions.

you need curtains that go to the floor or probably better to have a roman shade.

The bed seems really low. Can you maybe find a higher frame, or maybe find a way to elevate it?

an area rug would do wonders.

If your budget allows, a higher bed with a taller headboard would be very nice. I recommend an area rug too.

I agree with the other replies that a floor rug would be good.
Tiles in a bedroom are cold under foot. A nice plush rug would frame the bed and be functional too.
Your bedroom furniture is dark so instead of replacing it, which is costly, work with it.
Add a vertical striped wall paper behind the bed which will add the illusion of height. Go dramatic
Get some matching lamps as previously suggested.
Declutter those night stands.
Get some more structured window coverings such as romans(as previously suggested) or shutters which I love as you can control the light and they look so fresh and classy.
Go for white linen, throw a few complimentary cushions on the bed after you make it.
I can see this looking great.

If you have some money to work with ... I would put a floating timber floor over the tiles ... But a rug would be a much cheaper item ... Wardrobe appears to be missing doors but if budget allowed ... Would build in robe that goes to the ceiling for storage space to hide suit cases ... Then from there use soft furnishings to colour your room to your taste ... Have fun !

soften floor with a rug or rugs. SIde tables and lamps for sure! I don't like the vanity. Do you know Joss and Main? cool things on that website. It'll crowd up your email box but tons of ideas and themes. You need a theme that makes you excited or happy to relax in your bed. Remember beds are places where we dream. It looks like you are not dreaming or having dreams come true. But congrats! Change is afoot! Your future self is bringing it! Enjoy the transformation. Maybe time to get donations together from the closet too...?

oh, and ART.
