the curtains and the green wall are very dreary, you have blinds so I would try sheers.

Light wall to match the other walls, let the textiles be the feature.

nice prints, matted to show larger than they are. Simple full bed, no frills.

I would paint the room all one color, pulled from the floral bedspread. Go shopping for beds as it doesn’t seem like you have made up your mind what you want or even like. If you are set on keeping the dresser, why not google pictures of children’s MCM rooms? That might give you a direction and help choose frames for the prints also.

What does your daughter want? This room looks like a guest room or older persons room not a little girls. I would add elements that she would enjoy. The dresser seems too close to the bed. The drapes are a dreary colour. The wall I could work with if other things changed.

I’d paint the green to match the rest of the walls and ceiling.

And center the bed on that wall

I’d also change out the hardware. Maybe brass or polished gold.

Will look out for some new bed ideas

'The dresser seems too close to the bed'. Which is why the different bed!!! I love the window seat you've created but blinds aren't easy to rest against. If your daughter is old enough take her with you bed shopping! The pale green is a nice background for your florals. The dark wall seems over powering to me.

A new bed won’t dramatically reduce the length of the bed. The one in the pic is quite minimal.
