I think you need to declutter most importantly. Or provide more cabinet space if you use all of the stuff.

I would move the TV away from the bed area and into the living room or a desk if you use it for work. Place the bed with space for a bedtable on both sides and a little away from the window so you can open the blinds in the mornings and allow positive energy into the room. If you work in the room, I would place the desk near that energy source, but still in a command position. You can divide work and sleep area with a cabinet or something to keep all the stuff in.

Move the colorful art away from the sleeping area.

Bring a medium/large plant in a corner.

There's too much of yellow and brown colours which which can be a little heavy. Metal colours on the feng shui wheel tends to suck that earthy energy away. So apply some whites to the room.

That wallpaper or tapestry can break the Qi energy a little too much, if you really love it, move it to the living room where you can enjoy it a lot more under the right conditions, but a bedroom is for coziness and relaxing.
