Buy the bedding you love and then go from there to doing the rest of the space, paint is cheap so leave it till the end of the process and match to something in the bedding would be my suggestion.

Work with teen for the grand plan! Put in this website search box: teen... Look at teen magazines at the library for cool ideas. Think about colors, shapes, patterns. Your creativity has no barriers! Use two color combos that are easy to mix and match. Paint walls, furniture, etc. Think outside the box. Paint a desk two different colors - one on the frame and the other on the drawers. Paint an all over pattern on a tall skinny section of a wall. If you don't want to commit to paint yet, see what it'll look like with dollar store wrapping paper taped to wall. Make pretend wallpaper with paint and a stencil. "Shop" in your house before you go out. Sometimes we have stuff in one room (or basement/attic) that can be used in another. Look for fun, kitschy, or unique items, for visual interest, and for conversation pieces Go to garage sales and thrift stores for big picture books. Use for prints for wall art. Get frames there also, or at dollar store. Get dollar store wrapping paper that is really pretty, interesting, or geometric. Frame it for wall art. Look for bulletin boards at garage sales. Paint frame and use dollar store wrapping paper for cork part. Attach with rubber cement or similar glue. Look for throw at garage sales or thrift store in bright color. Fold long way and put at end of bed. Build a wish list and take it with you when you go out.

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.

Hello! No, well what i was thinking, was to paint two walls dark gray and two walls white.... then put ornaments up of a certain color. For the ornaments I choose gold... See below. This is how far I've got. But I need suggestions on what color to have my curtains and bedspread...
