I would definitely suggest you with Tan Brown Granite & Coffee Brown Granites Polished Surface.

With your original pictures - I agree with larger rug. But I don't agree with comments suggesting the rooms are monochromatic. They are lively indeed. I think you are just missing some accessories! Art work on the empty walls - even just a single large dramatic piece is in order. In the bedroom on the white wall, in the living space behind the sofa, in the greenish bedroom behind the two beds. Those are instant areas where you can improve. But I think your spaces are lovely and well put together. Also I agree with the comment about table lamps - some of those would really add something, and your coffee table looks so empty - maybe just one gorgeous bowl, or stack some books. These rooms are 90% done in my opinions, just need a few finishing touches. Some of my rooms come out like this because the clients are not willing to pay for those last few finish items or feel they can do that part themselves...

A good beginning would be to replace the walkway up to the house. A new brick walkway or stamped concrete in the same color as the brick on the house will pull all of the elements of the exterior of your home together. I made my walkway 3 feet wide with 2 feet beds on each side of the walkway in stamped concrete. Create the walkway at a distance from the house in an organic natural flowing pattern up to the house with planting beds flowing beside the walkway. Take the brick right up to the from door. Soften the entrance to your home by opening the planting beds up by the house into large organic shapes. That's what I did with my home and it changed it dramatically! It's a lot of work but what a difference!

If you love the marble tile, go for it! You can always buy a stainless or white range hood backsplash like this http://www.wayfair.com/Air-King-Range-Hood-Back-Splash-SP2430-AXK1174.html to slip in place when you are cooking something really messy. I have a travertine backsplash and use a stainless sheet when frying. It works great and no worries about stains ruining the stone.
