For me, your bedroom is missing two things - style cohesion and texture. For starters, I would replace the white pillow with two of these: [houzz=] Your bedside lamps are nice, but now with the gray comforter they need a new style: [houzz=] There's an outlet right where a headboard would go, so instead, I like this art over your bed: [houzz=] or if you prefer some color and something quirky: [houzz=] For curtains, see if you like any of these: [houzz=] or [houzz=] or [houzz=] For nightstands, try these: [houzz=] If you decide to paint your wall charcoal gray, be sure to add art with color behind the bed.

I think the first layout is fine. You might want to consider moving the door for the storage room of the master bedroom so that it opens into the hall. That way the kids can use it for overflow storage. Also, that hallway is big enough that I think it could hold a large armour, providing more closet space. (There's no need to sleep in the same room as your clothes, so long as they're not too far off.) Also, don't forget that while the drawing shows kids in double beds, this need not be the case, so there will be more room for furniture (dressers or whatever) in their rooms. Finally, that step to bedroom 4 will not be odd at all. I've seen it in other homes. It looks clumsy in the drawing but it isn't. What you'll see when you come up the stairs is a bedroom door on a slight diagonal. It's only an odd jagged step if you walk like a robot, in straight lines along the wall, which is what your eye is doing on the drawing but you won't do in real life.

As chookchook said in her recommendation about painting, put a drop cloth on the floor. Get a very safe ladder. remove the lightbulbs, and cover the outlets. Turn off the electricity to the chandelier. Then spray it with a mild cleaner (I use one I found at Target that's basically water with vinegar, until it's dripping wet. Start at the bottom and work your way up, so you don't have dirty spray dripping on the bottom of the chandelier.Work your way up and down until the dripping spray is clean. The chandelier may be gorgeous and expensive, but it seems totally out of place in the architecture of the room--more at home in a chalet than a sunny room with a window wall. I would probably try to find a way to get it removed, and sell it to someone who appreciated it better than I.

How about flanking the window will billy bookcases? Paint over the green wall an off white and just pick a color you love for the bed wall. A stylish chair for your desk and maybe "industrial" looking bedside lamps will "man" it up. :) Plus, get a cooler looking desk chair...in a color that you paint the bed wall.
