Were you meaning to add this photo from your ideabook? If not, I'll can go back and delete this reply.

Personally I like the ones you have but I know about storage issues, your room has grey tones so I would go with that if your couldn't find something in white. White always looks clean and it allows you to change the colours in your room, at a later stage without changing your cabinetry. I do like the chest of draws idea suggested by someone above - it was what I had thought of before I saw their photo - the low but wide ones in grey. You have plenty of room for that and it could make your room look wider. For me the eye sore in the room is the ceiling light fixture. Something modern / perhaps glass or a large circular pendant could be perfect.

I'm sure living in Sydney, you might come across what your looking for. Try going into ALOT of antique and secondhand shops, as they can be serious treasure troves right there. Also have a look at auctions as well, you can find really beautiful stuff there too! Also try websites like gumtree, eBay, etc.. you'll be surprised in the plethora of furniture being sold in those websites, especially princess style furniture! If you have exhausted all avenues and still can't find what you want, you might want to go to a cabinet maker/carpenter and ask to get one hand made. :-)

Looks great! I hope you don't mind my saying ... we have some lovely lamps and accessories for you're spruced up room :) although I can't see the rest of the room, the attached mirror comes to mind as a possible option for you.
