so i'm sensing you want a colorful/boho vibe. I think you could definitely pull it off if you incorporate some glam elements to tie in the silver/gray furniture. I don't hate the current wall color. I think you should focus on the furniture and decor.
would you consider refinishing the bed set? even if you paint just the gray strip between the silver and the upholstered part you could introduce some earthy brightness. I was thinking an olive green would work with the gray, but still give you cozy/earthy. alternatively, if you don't want to paint the set at all, contact paper or peel & stick wallpaper would add color texture, and you can remove it.
(idea 1) / (idea 2) / (idea 3)
a creamy boho bedspread will brighten everything up, and showcase any colorful pillows you choose. (like this)
and drawer pulls are a good way to incorporate some personality. maybe these or these which don't clash with the dresser, but are a little more fun.
I think a black pendant shade would go well in the corner for some ambient light (maybe this).
