The bed is too large for the room. Replace the bed with a full size platform bed with storage drawers underneath. Tada. Less crowded but more storage and cozy.

I think the bed should go centered on the wall to the far left based on when you walk in and the dresser on the opposite side then the dreamcatcher hanging in the corner between her bed and the window where it already is and her cross above her bed and her name letters above the dresser and then some nice curtains on the windows would look nice.

Just guessing that worth trying in the corner, jutting into center of room?

Where was her crib in the room? I think a twin platform bed with a lower headboard and some storage underneth would be a great idea in a small room then just clothes she wears all the time in the closet .Leaves a bit of play space too.Her bed could be right against the wall along that wall to the right of the door

Yes I would remove the footboard, and add some nice skirting and a nice canopy over the bed would be pretty.

You could also use the footboard as a headboard so it won't be as high.
