You are likely to get more responses if you post this on the Home Decorating forum along with a photo of the room.

I would need to see pics of your space and also usually a color palette for a bedroom starts with the bedding so post that too.It is also very helpful for you to post pictures in your idea books

IMO you start the palette for bedroom with the bedding and I need pictures of the bedroom with the furniture that is staying in the space .

If you prefer a blue or green room that coordinates with art, another artwork with a lot more blue or green would be better, like this https://canvasprintshere.com/prints/timothy_easton_reflected_clouds_oxwich_beach_art_print-18681.html The sandy wall color that's there now is actually a good choice for your giclee canvas artwork above. BTW, it's much easier to pick a new paint color after priming the walls with white primer.
