It's very hard to make suggestions without pictures of your room as it is now and some indication of what you really would love to have in there. I see from your idea book that you seem to like vibrant coral pinks. That might be a place to start -- to find bedding you love with that colour and others in it and then use those colours to build the room. You will need to decide, though, whether you want a room with lots of contrasting colours in it, or whether you would prefer the coral to zing against neutrals (you have some very attractive neutral rooms in your idea book, as well as brilliantly coloured ones). But there's also the issue of furniture style -- what would you like, what do you have that you need to keep, what might you paint to change its look. And the issue of your interests: do you want them reflected in your room (sport, music, dance, animals, whatever?) Lots to think about!

I love this room! I'm looking for ideas like this!

Photos of the room would be helpful.

If that's what you like, do it. Blackboard chalk on the walls, do the drawings yourself or bring in your talented friends. Get fabric just like that to cover your headboard. Match the bedspread and cushions as closely as you can, or find something equally colourful and fun. Then play with the rest of the room. Pick up the colours from your bedding; paint the other walls and furniture, hang drapes. It's all there, just within your grasp. I think you want crazy you, not something sane and within the rules. Have a ball.
