Here’s an inspiration photo for color choices. I like the very soft paint color. I think there should be much less contrast between the wall and ceiling. White drapes look great in this room. I love the colors in your art and would think about using a bit of that gorgeous blue somewhere, perhaps in your throw pillow selection. The two paint samples are from Benjamin Moore.

I would paint the remaining walls the same as one of the colors in the wallpaper.

start by selecting your linens first

Before you get color, I'd focus on the layout. Do you intend to keep the sofa where it currently is? Do you want to keep the mirrored bedside tables? I think it is all too crunched together. Will you keep the lamps and the chandeliers? Are those square poofs staying? Do you want to keep the walls the current color? I think that wallpaper is overkill in this space.

I hated my mirror top tables. Dust in 30 minutes. You know what I'm talking about I'm sure. Get a frosted piece of glass cut to fit the top. I did and it makes it more tolerable.

I would not paint your dresser, but these glass lamps look like they would work really well to tie everything together. I would also try hanging your pic vertically (counter clockwise 1/4 turn). You may need to scoot the sofa to the left some and lose the side table, but I don't think it will matter that it's not centered with the sofa.

Also, you might consider looking for wallpaper with a bone colored background to go with your headboard instead of the bright white.

It looks like you have a nice ‘glam’ theme going on with the wall paper, bedhead, mirrored nightstands and sofa all working in this direction.

The dresser and tall boy don’t quite fit, but painted white and maybe with a switch in, could tie in nicely.

Perhaps you could build a color scheme on white, silver/grey with pops of pink and blue?

Sorry, I meant above, ’a switch in’ hardware..
