I'd suggest you have a look through the photos section on Houzz - or there's quite a few good articles on how to decorate :) maybe both you & your wife could save pictures to an ideabook with a few words on what it is you like about each one, and it'll give you more of an idea of what type of things you like? I think colour-wise, turquoise and peach can go together really well - maybe a warm cream colour on the walls & pops of turquoise and peach in the form of throw cushions etc.? Again, just searching on Houzz can give you some great ideas - just literally searching 'turquoise and peach' brings up quite a lot of pictures :) to get you started I've just picked out a few which I personally think work well :)

The above is really the best layout for your bed and you could add a bench at the bottom. If you want to make it different, if it fits, you could try bed across the corner on the right. You can achieve a unique bedroom by its decor though and place furnitire where it works best for circulation. In regards to the sitting area, given the narrow space, if it's wide enough try a love seat across from bookcases/including tv and fill shelves with great accessories. Use wallpaper for added interest in either room.

Unfortunately, I do not have a photo for you and have been unsuccessful in downloading my sketch. I think I can explain better what I meant. Your window behind the bed cannot be centered behind the bed and presently looks a little awkward. To remedy this, I suggested framing it with wood trim and creating another "fake" window alongside of it also using wood trim to frame it. Both the fake and the real window would get two rows of louvered shutters, a top row and a bottom row. Obviously, the lovers on the fake window would remain permanently closed. They are there only to give the illusion of another window. The shutters on the bottom half of the real window would remain closed, but the louvers would open to allow light and air. The top shutter could open to access opening and closing the window but most of the time, just have the louvers open for light and air. You will have created a bank of window that your bed could be centered under and I think it would look nice. I would use a headboard with wood or metal spindles that allow the light and air from the real window to pass through, yet give you something to prop pillows against. I must say though, if you did not want to do this, I love the recently added photo by Anne dee with white drapes, gray walls and some framed pictures that really help balance the awkward window. That was a beautiful room and looks a lot easier to accomplish than my idea. From your photos, I am not quite sure you have enough wall space to do it exactly like that, but I am sure you could experiment with the concept and come up with something lovely based on that idea.

Nice size, but a bit skinny! So, you need "zones." Near the balcony, perhaps a couple of small chairs and a table for the view, or a chaise with a reading lamp. Then, the sleeping area. Then some additional storage near the dressing room, if needed, and finally the bathroom.
