Hi Ju, I looked at your idea pics and they are all very light and neutral. This room doesn't seem like it is really you. If I am on the right track, I would recommend a colorful area rug, a light colored cover for the sofa bed and a colorful throw over the back. A row of framed prints or photos (18" square or close to that size - not too small) on that wall would give more life to the room as well. Two white filing cabinets could flank your desk along with a sleek white leather/chrome chair. Need to brighten it up!

Especially with the amber-colored glass at the top of the window, orange and pink would be nice for this room.

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.

Hi Bradford Rice, I understand that it can be difficult to decorate for someone this age. The best place for you to start is to specifically ask him some leading inquisitive questions like, "What do you like to do most?" "Whats your favourite part of your room and your least favourite?" If you can find an item which is dear to him (like his guitar, or playstation remote; yes I did say that! or favourite sweatshirt) then this gives you a springboard to build from. There are some amazing wallpapers out there (check out Mr Perswall graffiti range, or distressed timber board wallpaper) which without too much investment can transform a room quickly. Try to simplify your colour palette and limit it to just a couple of colours, dirty pinks are in vogue along with greys, and animal skins, remember that bedding colours bring a whole new feel to a room and if it lacks natural light keep the colours masculine but subdued with a taupe linen bedspread. Incorporate some chunky texture if you can by way of a thick weaved carpet rug or woven rustic lamp shade, and some shelving storage to encourage him to pick his stuff up off the floor! Good luck with that one! Post a pic if you want further advice.
