Its a really lovely room! what a great place for kids to share. I like kids sharing rooms. I think you need another colour to tie it together. I would suggest a blue tone.... teal, navy blue, duck egg blue. to tie it together. Its a little to pale and looks sparse, but actually isn't. I would leave everything exactly as is, BUT, paint the back wall behind the bed teal and find a simple navy blue wall decal that is fun and kid- like maybe one with a sillouette of a boy and girl playing. I would paint the wall behind the sofa duck egg blue. Then I think it would suit both kids more and look more kid friendly. the blues will balance the pink and cream, but because you have a pale carpet i don't think it will look too dark. don't worry about making it totally kid like, its a room they will grow with, not a kindergarten, and it also needs to peaceful and restful for sleeping. besides with their art on the walls and bright toys everywhere it soon looks bright and kid like. Good luck!

You will need to talk to an architect or perhaps a glazing vendor who specializes in curtain systems. They will likely provide the shop drawings necessary. Curtain systems are not something I'd attempt without help if you aren't an architect. There are too many variables, too many different ways to go, lots of options (storefront, spider, etc).

Ok there is a lot that you can do to decorate this place. You can put nice white/cream curtains along with white/cream curtains so that you can use net curtains one when you want more light. You can place a small decorative plant on that window. Another thing is that you can do is cover the wash-basin pipe. You can use a couple of small frames to hang on the wall that compliments the color of the wall. Talk to top interior designers such as Tasko.

I would like to give you more suggestions to improve your living room ambience . The highlight wall in pink can be switched to some other striking color such as a teal blue or moss green color , then you can change the curtain to from sheer/transparent to a thick fabric and the color to a neutral tone such as white / beige /grey .And yes definitely adding more lights to the space will amp it up .. Hope it helps!
