OK - I'm a beginner here on Houzz so my opinion isn't worth a lot but here it is: the room is a bit bland and lacking in character. I think you have to find some pieces you really love to bring it alive. All the suggestions are good for widening your horizons, but ultimately, you need to find things that matter to you, because it's your home and not a magazine photoshoot. That said, if it were me, I'd throw a couple of small, colorful rugs down, and put either one large painting or three smaller ones over the bed - not in a line but at different heights - to break up the binary look. I'd also put something on the wall above the heater. Then, play around with a few cushions and maybe a quilt that picks up some of the colours in your artwork.

Nice reno :) Few things imo... don't think you need any artwork next to the hexagonal mirror, it could get too busy, if you're after a more balanced look I would move the chest of drawers & mirror to the left more centered on the wall, then relocate the white rack to the other side near the door in place of where the bin is now, not sure the bin should be a feature and be the first thing you see when entering the room, if the drawers have moved that far corner may now be better for the bin... yes the wall above the bed definitely needs some artwork, which I think should be as wide as or wider than the bed, if a large artwork is too costly maybe three squares alongside each other to create the width, stick with the style of the room (can't quite work it out) and pick colours to complement the more permanent fixtures like the blinds rather than colours from the bed linen etc which will change

What emotion do you want to feel in the room? Calm? Energized? Happy? What colors do you associate with the emotion you want to have in the room? Choose a bed covering first. It is much easier to match paint to a bed covering than it is to try to find a bedcover to match paint.

Duck egg blue (to go with feature wallpaper) , silvery grey, peachy pink or pink paint colour for my bedroom walls please.
