Hi, I much prefer the bed on the gable end wall and the desk flat against the wall with the door. Love colours and bedding and lamps. I would also consider a large piece of artwork over the bed. This option below might be nice but on either side of your lamps as they are quite tall.

This is another nice layout of artwork that runs along the top of the lamps and headboard.
Mirrors or one large long mirror are also an option.
One large painting, either long like this one or one with more height to accentuate the gable wall.

A more sculptural item is also an option
Also, try the picture that you already have in your bedroom, and see how that works, and you might add in two small mirrors on each side if the picture is not dramatic enough on its own.

Can you repost this with the pictures flipped properly?
