This is a dilemma indeed! Posts in the middle of rooms are always a little difficult. It would be helpful to have pictures of all four walls to suggest the best layout. From what I can understand of your dilemma, I've attached a layout that may work based on your description. It features a defined entry. So when you walk through the front door, you will see a console table with a couple of ottomans stashed beneath. They can come in handy for extra seating. In front of the console are two arm chairs, followed by a modular sectional - they make up your main seating area. To the right of the kitchen door is a TV console. Behind the sofa is a bookcase and to the right is a round table with a couple of chairs for games, paper work or what have you. You don't mention any windows. Is this the case? If so, we'll want to make sure you've got adequate lighting and colors that will work with the limited light. Hope this helps!

There are many photos of artist's studios on this link: http://www.houzz.com/photos/home-office/query/artist-%2B-photographer I'd display some of your work as a part of the decor. click photo 1 A working studio. click photo 2

For the living room, the focus should be the balcony area. So flipping the couch to face the wall and not the dining table will help. Kind of like this pic. Even if you already have the sectional that is in the diagram, you should be able to flip it. In fact a sectional would probably work better than the couch in this pic. I also really don't like the style of this pic, but it showed what I meant, For the girls' room: No matter which bedroom you choose, you should maximize floor space so that they have the biggest play space possible in their room (as they get older you can add desks for school work and such). To get this space, I would give them bunk beds. This configuration gives them an open feel and more storage, essential for girls. You posted two different kitchen designs. This makes it hard to give you advice. I agree with other posts that your sink should be away from the wall. This allows you to have stuff to the left of you (drying dishes in my house), while you wash vegetables on the right of the sink. You need the same space on both sides of the stove, also. At least 24 inches on both sides is good. 36 is better, though. The first design has a nice little countertop space that adds a place for your daughters a space to sit a watch/ talk to you while you're in the kitchen. When they added this to the first design, you lost cabinets on the other wall. This is bad, as the space is already storage limited. Try making the rounded countertop bump out into the living space more. If you play with the shape, you could make it work without losing the cabinets on the other side. It doesn't have to be rectangular or a perfect circle. You can see how this one isn't confined to the floor plan of the kitchen. I think this is what you would need to do to make it the most functional.

I think the L shape sofa will look good, with the corner of L placed where you have the Ganesha Idol. you can also place a bench on the opposite side with some colorful cushions on it. It will give you a contrast look and a antique touch to the hall. You can place the Idol elsewhere in the hall, may be just opposite the door ttowards the call. so that whoever enters from that door feels nice/good. I have selected light colors for your hall because your hall has dark color wood work and its making the hall dark. Light color makes your room more bright as you have lot of sunshine coming from the door and windows . I hope this helps. https://www.bing.com/images/search?view=detailV2&ccid=4P6z03v6&id=A25E4EEE0B66770D19E09A1F431B9BA642F3D345&thid=OIP.4P6z03v6cAWvmAYfClS2WAEsCc&q=l+shaped+sofas+designs&simid=608018563129935084&selectedIndex=107
